I really like Defold, have used it for a number of small games I've developed for a side hustle.
It’s the problem with this whole Unity crisis. Every other engine out there is… small. I have a 50+ person team with a big open world game and I’m basically fucked into accepting whatever Unity wants. I can’t just switch engines with four years of tech and team experience. And Unity knows this. It’s so fucking slimy and malicious.
This is why I only use Open Source... if you build on a proprietary platform, the owner of that platform can change the terms at any time and you are stuck with a massive cost to change, or you just pay the ransom.
In a competitive marketplace it can be hard to accept less than state-of-the-art.
That said, we are seeing that it might be worth starting out on an open source platform and dig in to make it state-of-the-art.
Not everyone is interested or capable of doing that, though.
Godot is well on its way to replicating the same kind of phenomenon Blender has succeeded at.
This can't happen to you if you use Unreal Engine.
Can't Unreal change their pricing model overnight?
Only for future engine versions - you are able to continue developing and release your project with the one you already have under the previous version of the terms.
That is nice and all... but you still have to invest significant resources into building and training your team to use Unreal, and then if they change the terms for future versions, you are stuck on an old version if you don't accept those terms, until you retrain everyone.
Of course, open source projects regrettably become closed source projects sometimes too (see Hashicorps recent moves), locking you into the previous version of the project.... but, with Open Source, you can fork the project and continue- or ally with other members of the community to fork- often at a lower cost than re-training and re-tooling. An option that does not exist in the proprietary world.
The thing is though, there is no open source project even close to what Unreal Engine currently offers. It's just lightyears ahead in everything kinda? Editor tooling, asset pipelines, advanced rendering features, ... While you could build on open source tech and implement all the missing pieces yourself, that is just not going to be a sensible investment for most studios.
You'd be hard pressed to compete with Epic Games' investment in the engine for their own games and others, too. I don't think this situation is comparable with Hashicorp. Epic has more than a hundred engineers continuously improving the engine, doing research on new technologies like Nanite and similar, and all their improvements are available to you immediately. You have full source code available and are able to modify it as needed, you can also fork it under the current terms. As far as I know there were never any forks with significant traction, only to implement random features people needed in their game.
This is just a guess, but I truly don't believe we are going to see Epic Games turn evil like Unity has as long as Tim Sweeney holds more than 50% of the shares. Going public was Unity's death sentence - the tech no longer mattered, now it was all about extracting the maximum value possible before the company is run into the ground.
If every company that currently pays Unreal licensing fees instead donated half of those fees to Godot or O3DE, I think we would rapidly see the gap close.
That is obviously wishful thinking and probably not a good bet for a game dev company dependent on cutting edge Unreal features to make. However, not all game developers are in need of cutting edge, for many, Godot 4 will offer them what they need already. O3DE looks interesting, but seems only really currently usable by a company which plans to do a lot of custom engine work themselves already.
I am currently trying to learn Godot 4 in my spare time (which unfortunately I don't have enough of), and if I ever start to make money off it, I will be donating a percentage back to Godot development. I certainly don't begrudge a developer going with Unreal, but I encourage them to look at alternatives and what they really need to plan for the future and not be tied into the present situation.
My goal is to make some really good games in my 40s - a decade from now. So I might as well learn skills and build up on open source now. That fits that timescale.
_"Today is the first day you have make changes."_
Unless your team's business model is to _be a Unity team_, it is a matter of determine your goals, evaluate options, get buy-in then start making changes every day to generate that outcome. Don't sell it as a "I hate Unity." Sell it as "it is time to consider how we maintain our future by diversify our skills."
For someone who's completely out of the loop, what changes are the Unity peeps doing to their business model?

If Unity isn't so big it won't be a crisis, obviously.
I've been seeing a ton of game engines on hackernews in the last couple days.
I think many hobby game developers don't realize the astounding important of designer oriented tools. Even most game companies have coders create designer oriented gui tools for games to be more productive.
Whatever open source engine cracks an easy 3d player controller, dialogue system, human retargeted animation system, and easy editor extensions will KILL the competition asap.
What's really missing is one (or multiple) open source "bring your own engine and asset pipeline" editor tool(s).
Game editors have pretty much all arrived at the Unity scene model and editor workflow (game object outliner to the left, scene view in the middle, property panel on the right, asset browser at the bottom, plus floating panels for things like animations, material definitions, game specific data, or anything else really - everything needs to be extensible through scripting).
The Unity Editor and asset pipeline is hackable enough to use it as editor for another engine, I did that in the past as "proof of concept" and it definitely works, but is most likely a legal minefield.
Blender is also definitely hackable enough to serve that role (see: https://armory3d.org/) (again I did something similar in the past with Maya, it kinda works, but this wasn't very popular with artists because they were overwhelmed by the unfamiliar and complex Maya UI).
PS: the Defold examples page is actually really cool, with realtime examples running in the browser:
> I did that in the past as "proof of concept" and it definitely works, but is most likely a legal minefield.
I really wonder how dangerous it is legally. I'm already been (slowly) writing a rust tool to convert some Unity .meta for bevy engine before the Unity pricing crisis.
Something language server-esque could be really cool as well as a means of exposing the engine and pipeline to the editor.
What about Wicked Engine?

> 3d player controller,
Unity has no this built-in.
> dialogue system,
Neither.
> human retargeted animation system
Unity has a built-on one but it's shitty.
Yea most indies buy these assets from the unity store.
If a new game engine emerged with these, they could take most of unity's market share without needing an asset store of their own.
I'm waiting for an editor aimed at the programmer. I really dislike unity.
The Defold editor was written in Clojure, is this still the case?
And thus gave birth to cljfx, which are quite nice bindings to JavaFX (once you get your head around it all).
There's a good amount of it in the repo, according to GitHub.
Not actually open source. This is yet another instance of a project eager to reap the rewards of being associated with "open source" without committing to it (i.e. with a license that would make it so). Defold is source-available and some flavor of royalty-free with limitations.
It's actually worse than that, though, because it goes out of its way to obscure the license terms; in this instance, they're going for association with the cachet and warm fuzzies of the Apache license by throwing that name around, despite not actually being Apache licensed. This is not the result of oversight or ignorance. It's intentionally deceptive.
For anyone who thinks that I'm reading between the lines and overstating this, you can refer to the last time this came up. They received sufficient pushback about their messaging. They're not just aware of the discrepancy between the consensus definition and the way they're using it, they acknowledged it explicitly. In response, they said, "We are humbled [...] also sorry for misrepresenting the license" and that "We have updated the website to reflect this and we no longer use the term"[1]. In 2023, there's a big fat nav item at the top of the site that says "Open Source". You click it and read the fine print which gradually reveals the truth of the matter. The "open source" part refers (apparently?) to... their extension ecosystem?
Everything about this screams, "We know exactly what we're doing, but we're going about it in such a way that we can claim plausible deniability."
I'm reading between the lines and overstating this, you can refer to the last time this came up.
"Open Source" was wrongly added to the title by the poster. It's not used on the site to describe the engine.
It is literally in top menu bar.
Leading to page that says that Defond is not actually open source.
"has navigation that takes you to open source stuff" is not "claims it's open source". The title is just wrong and they have clearly fixed the thing people were complaining about last time. It's not reading between the lines, it's simply misreading.
> we no longer use the term "Open Source" as to not confuse it with the OSD.
<https://news.ycombinator.com/item?id=23235217>
What am I misreading?
They don't use the term "Open Source" to describe their engine. They used to, years ago, and now they don't.
> We have updated the website to reflect this and we no longer use the term "Open Source"
They didn't say they were going to "no longer use the term (with respect to the Defold engine)". They said weren't using it. Why? Precisely so "as to not confuse it with the OSD". Let's recap:
They used to use the term "open source" (one part of an overall effort to misrepresent themselves and their work). Then they said they took it out—which means that if the term is there now—and it is there now—then they either didn't actually take it out, or they took it out and then put it back in, even after saying they were "sorry for misrepresenting the license under which we make the source code available".
Prevaricating on the whether or not a known bad actor is technically wrong in sidling up next to a line they've already once crossed isn't a defense of the subject of here—because the subject is not strictly confined to whether or not they are crossing it now. It is the very fact that they've indisputably crossed line before, admitted to it and issued a presumed sincere apology when called out, and yet here they are—reaping the rewards of the misleading[1] way in which their messaging is being perceived (again).
'Prevaricating', 'known bad actor', all of this is your gloss on something that happened 3 years ago and a response to the wrong title. . They didn't write the title and have a nav bar that mentions open source. Lots of companies with closed source products have open source navbars, entire open source-titled sites. It's a boring high-dudgeon tangent.
> 'Prevaricating', 'known bad actor', all of this is your gloss on something that happened 3 years ago
My "gloss" of something they themselves acknowledged—how are you not getting this?
It's like if someone gets charged with something, briefly attempts to maintain some dubious and not-terribly-convincing story that they didn't do the thing, but then does eventually cop to doing the thing, gets a light sentence for having acknowledged that they did the thing (maybe even cheered on for their humility in doing so), and then three years later upon having some new sketch called out, defenders leap up saying, "oh, well that's just your take; prove they'd ever done that". They already acknowledged it themselves; that's not a "move" that's available to you anymore, bud. These are total motte-and-bailey shenanigans.
> and a response to the wrong title. . They didn't write the title
I flag comments that complain about titles. Between the two of us, you are the only one to have mentioned the title of the submission—which isn't even the title anymore. (Repeatedly. Why?)
You can continue to try to get me to direct my attention to the title, and I will continue to ignore it and limit my comments to what's actually at issue. Go ahead and keep strawmanning the shit out of me, though. Maybe it'll stick.
The issue is that there is no issue other than the title being wrong in a triggery way - as you personally know, people care about this sort of thing a lot but in this case it was a simple mistake by the poster. I emailed the mods and they fixed it. The other thing was fixed by the makers of this thing three years ago.
Let's make it stick by wrapping up here.
I don't care about the title. As you know, the mods have changed it. And it has nothing to do with the discussion, besides; the cooperative principle means that it's not enough to say something true—you need to say something true and relevant.
<https://en.wikipedia.org/wiki/Grice's_maxims>
This is the issue: you are in the untenable position where...
- those you are defending had a charge leveled against them
- they have acknowledged that they were doing it—there is no cloak of plausible deniability here, and yet
- you are defending them on grounds of plausible deniability, anyway
So square the circle—and stop mentioning the submission title. (I'm not interested in the title. Nobody is.)
the untenable position
I have received your letter of this date containing the terms of the surrender of the Army of Northern Tangentia, as proposed by you. As they are substantially the same as those expressed in your letter of the 8th inst., they are accepted. I will proceed to designate the proper officers to carry the stipulations into effect.
I know what I'll do is, I'll capitulate to the fact that there is nothing by way of relevance favoring my side and I have exhausted all attempts at misdirection, but I'll simply tell them that they are the ones capitulating. That should work.
In my opinion they intentionally keep it misleading. And fact that every once in a while someone posts about their project with "open source" in title is good proof that it does confuse a lot of people.
It's proof that someone got something wrong in a title, a thing that happens on HN multiple times a day.
It's close enough. You can use the engine to make whatever games you want, modify the code, rebuild it, etc and profit from the game you create.
You're not allowed to fork and then profit from the engine itself, or the editor. That's a really important distinction, and you're right that it should be highlighted.
But it seems very reasonable to me. Any real game dev won't care about that. Basically, you can't resell the engine, but you can do anything you want with the games created by it.
"it goes out of its way to obscure the license terms"
They make the license terms very clear. Their license page highlights the differences to the text of the Apache 2.0 license. The only change is that you can't sell the engine itself. https://defold.com/license/
"intentionally deceptive" "there's a big fat nav item at the top of the site"
The Defold guys have released multiple components on Github with the MIT license. The fact that a navigation item is named "Open Source" does not say that all or most of the software from this company is Open Source. For example, the fact that the Apple developer site has a navigation item named "Open Source" similarly doesn't mean that all or most of Apple's software is Open Source.
"Everything about this screams"
You're attributing unverifiable negative intentions to the Defold developers.
This, the last HN thread about this, and other similar negative feedback create an incentive to avoid the term "Open Source" in order to steer clear of potential negative publicity for innocent misunderstandings and different opinions.
But they also have an incentive to keep the words "open source" in a sufficiently prominent position on their website to ensure that search engines list their page in the results for the search term "open source game engine", since it's a relevant result for almost all people who search for that term.
> You're attributing unverifiable negative intentions to the Defold developers.
I'm attributing motives to them based on their own admission—that they were misrepresenting their project. There's nothing unverifiable about it. They posted on HN and tweeted about it—their own words. It's not reaching on my part. (Why are you, like other commenters here, so attached to the plausible deniability angle? It's not available anymore. It's gone.)
> they also have an incentive to keep the words "open source" in a sufficiently prominent position on their website to ensure that search engines list their page in the results for the search term "open source game engine"
Uh...? Giving an accounting of the incentives isn't exculpatory.
Thieves have an incentive to take things that aren't theirs. Liars have an incentive to tell people things that aren't true. Cheaters have an incentive to have sex with someone who isn't their partner. We already know _why_ they want to do it. That wasn't ever in dispute.
> This, the last HN thread about this, and other similar negative feedback create an incentive to avoid the term "Open Source"
This is as baffling of a remark as the earlier one.
By "avoid the term" you mean "avoid misrepresenting the license under which they're really making the source code available".
Prosecuting murder is a form of negative feedback that discourages people from carrying out murder. This is known. It's not an unfortunate consequence. It's rather the whole point.
I think you're being too harsh.
The main item on the landing page says "free to use" and "source available", while that "big fat nav item", that doesn't show up on mobile without clicking on the navigation, clearly states:
> Defold is a source available game engine with a developer-friendly license derived from the popular Apache 2.0 License.
And under "Open source":
> A large selection of official and community developed open source extensions are available through the Asset Portal.
I think this is clear enough, and doesn't seem like they're abusing the open source terminology. Whether you agree or not with their license is another topic, but their copy seems clear to me (an OSS enthusiast and first-time visitor on their site).
That said, the title of this HN post is misleading, and definitely needs to be updated to reflect this.
> Everything about this screams, "We know exactly what we're doing, but we're going about it in such a way that we can claim plausible deniability."
(Feel free to address literally any of the pre-emptive points I made in my post, rather than responding as if I didn't already make them.)
You could cut to the chase and point out what isn't open source. Also, if that source is available, you could point out which definition of open source you are going by.
Oh, and please don't say "the standard definition", because that is definitely contested, even after all these years.
> You could cut to the chase and point out what isn't open source.
That's easy: Defold (the project linked here).
> Also, if that source is available, you could point out which definition of open source you are going by.
That's easy, too: I'm using the same definition that the Defold developers are using.
Your objective points were addressed. Any response to your subjective point "Everything about this screams X" would itself be subjective and not conducive to productive conversation.
That the developers have already been caught with their hand in the cookie jar and called out on it and apologized once before (for, in their own words, "misrepresenting the license"), and they stated that they would/did remove the term "Open Source" from their site precisely in order to not confuse the issue...
... was, in fact, not addressed.
To the extent that my comment contains speculative claims, the charges are aligned with the developers' undisputed past behavior.
And given that it's blatantly obvious what's going on, even without their previous admission, no one has any obligation to pussyfoot around on things like giving the benefit of the doubt. There is no doubt here—no reasonable doubt, at least. Only willful mendacity.
It is very clearly not open source nor is it claimed to be open source. They take great pains to explain their structure.
They are not being willfully mendacious. You are being willfully dickish.
Please don't cross into personal attack or call names in arguments. We're trying for something different here, and you can make your substantive points without that.
If you wouldn't mind reviewing https://news.ycombinator.com/newsguidelines.html and taking the intended spirit of the site more to heart, we'd be grateful.
to be actually honest, I tend to distrust anything that comes out of people who go out of their way to weasel their words like the maintainer of this project.
