Unreal Engine 4 Is Now Free 143

jones_supa writes In 2014, Epic Games took the step of making Unreal Engine 4 available to everyone by subscription for $19 per month. Today, this general-purpose game engine is available to everyone for free. This includes future updates, the full C++ source code of the engine, documentation, and all sorts of bonus material. You can download the engine and use it for everything from game development, education, architecture, and visualization to VR, film and animation. The business scheme that Epic set in the beginning, remains the same: when you ship a commercial game or application, you pay a 5% royalty on gross revenue after the first $3,000 per product, per quarter. Epic strived to create a simple and fair arrangement in which they succeed only when your product succeeds.

          To be clear though, it was that zealotry, attacking any piece of software that isn't under a license such as the GPL that I was poking fun at. I think it's naive to think that we'd be where we are now if literally everything was 'free' via something similar to a GPL license.

      terms are pretty fair actually.
    • Depends on who's freedom you want to respect.

    • I can't find references to the actual license text, but the expectation of paying royalties back to Epic certainly makes it non-free with respect to software freedom. This makes it incompatible in the same sense that the Creative Commons License's "noncommercial" clause is incompatible; most copyleft licenses insist on unrestricted redistribution (which would be broken by a requirement of paying royalties).

        And this is unprecedented because it's not two generations old. This is their current tech. If this isn't unprecedented, then who set the precedent? Not Id, they never released their current tech to everyone for just a royalty agreement.

      Of all the things that benefit from being free software, games aren't entirely gaining. A game with source code include all the "spoilers". Part of the magic of a new game is exploring, not drudging though code (an entirely different game). If there is anything given less criticism, let it be games. Sometime it's entertaining to be surprised. That is a games intended purpose, to entertain.

        Already a few disappointments. One is that the installed app is around 250Mb for what is effectively hello world. Also the whole environment is slow as molasses and I have a mac pro 2013. On the good side I think that I could develop just about anything that popped into my head. I am a bit worried about this being one of those silver bullets where the normal parts are developed so quickly that the project is seemingly 90% done in no time but the fiddly bits then take 10x as long. One other thing is that I like to release my iOS apps going back to iOS 5.1.1

        I love cocos2dx but I am starting to balk at the 2d part. They are introducing 3D so that is good. The documentation for cocos2d is sparse. The executables are small and the startup delay isn't too bad. It is 64 bit for IOS (critical). Very multi-platform (Win, Mac, iOS, Android, Linux, and I think mobile windows). Their release schedule is very fast. Also the C++ is pretty close to the bone which means that the project sort of marches forward at a steady pace including the fiddly bits.

        I recently played with Gameplay3d and was actually quite impressed. Very simple and it just sort of works. The only huge thing was that importing assets in from something like Maya was cumbersome and sort of sucked. The documentation is nearly nonexistent (documentation with useful examples) their sample code was trying to show off how they were such efficient coders and didn't separate out each bit of functionality.

        The platform that attracts me the most is Openframeworks. Except that they don't yet do 64 bit on iOS which is a show stopper. They are promising this with their 0.9.0 release.

        But I might have spoken too soon. I am going to continue now with cocos2d and probably deploy version 1 of my present project in that. But I am going to spend an hour an evening seeing how hard I can push Unreal.

        What worries me is that with Unreal I might alter my game to fit their environment which might make for a very beautiful game that isn't much fun instead of the ugly game that I make that is fun.
      • One other bit; I looked at godot and I would suggest that you just jump in with cocos2dx. It is great if you are 100% 2D. What I am looking at doing is what some call 2.5D and this is where I am having the most problems with cocos2dx.

        The experience using the development environment of Unity/Godot/Unreal is completely different than Cocos2d. Coding in Cocos2d requires you constantly be reading docs, hunting across the net for examples because the docs are horrendously incomplete and outdated, and doing all the coding and asset management by hand. There is a studio editor for Cocos2d, but it is difficult to use and the documentation for it is limited. I never managed to get it to work. Part of the problem is that much of the development of Cocos2d takes place in Asia, so the docs need to be translated to English. By the time this happens, they no longer represent the current state of the library.

        If you try making a simple loading screen and short game in Cocos2d compared to Unity/Unreal/Godot, you will instantly see how very different the two are. The learning curve for Unity-like development is really low. You can start on your game immediately and learn as you go. Cocos2d has a huge upfront learning requirement, and it's hard to pass because of the state of the docs. Frankly, I'm surprised at how many games are made in Cocos2d given the other offerings that are available which include a strong development environment. The biggest pluses to Cocos2d to me are that it's 100% free and that it has great crossplatform capabilities. But when you consider how much more difficult it is to use, and the fact that your game is unlikely to ever make money or cross the royalty threshold, you probably should be using an easier tool that is more popular and might lead to job opportunities. A lot of great engines are offering a free-to-start-with option: Unity, Unreal, Marmalade, Corona, GameMaker, Shiva, Stencyl, Construct2. Many of these didn't use to have a free option other than a 30-day trial.

          The thing is they're not doing any extra "work" as such, simply letting you copy the game engine, source code and all, has an almost zero marginal cost to them. So no doubt you think it should cost you a flat dollar or something.

          In the real world, they have had to invest a lot of money to create the game engine, so it is entirely fair that they want to make some money back on it if it is used to make a commercial product.

            • Considering all the the Harry Potter films lost money, apparently they do.

              I think the reason that it is not so bad for the feds is because the gross still got declared as someones income. So they still got to tax every cent pf the gross, it just showed up in other peoples and businesses financial statements.

        • So what would be more or less "fair" about altering the percentage based on total revenue?

        • Like one investor once said to me. If your product is good enough to sell on a royalty, whoever buys it should be more than capable of capitalizing on it's success. If 5% is too much for you to make money on you should look at other options.

          The royalty system has existed for a long time and many people got rich both from the royalty and from taking advantage of the success of the one selling the royalty.

          If you read the license agreement, the 5% royalty is only taken after the first $3000 quarterly. So as a developer if you make $10 000 per month (after store fees), the royalty will cost you ((10 000 - 3000) x 0.05) = $350. That leaves you with $9650 per month.

      Development cost for these things is still pretty close to half the whole cost. If you think making an engine from scratch is gonna cost you less than 5% (though do take in consideration the cost of learning/using the engine is, as that's not zero), go for it. Some companies still do it. Fewer and fewer though.
