I've always wanted to know how the 5% royalty is enforced. Other, much lesser known, engines have attempted to do something of this sort by acting as an interm

  Lawsuits. I imagine the revenue distribution would follow a power law here. So it would only really make sense for Epic to go after non-compliant "whales", where the unpaid royalties exceed the legal costs. Also, the more profitable the project, the lower the non-compliance rate, probably. It makes little sense to defy the royalty agreement if you have a successful project.

    To handle noncompliers, they can get off of the various App stores with a simple DMCA request, no complicated lawsuits required, unless the developers appeal the take down, which probably involves a lot of "under penalty of perjury" lying.

      Why would breach-of-contract have anything to do with the DMCA?
      • timv 12y ago
        I assume cma is suggesting that the contract would allow Epic to revoke the license of anyone that failed to pay their 5%. Once Epic exercises that right, any further distribution of the product would be a violation of Epic's copyright and Epic could file a DCMA takedown.

        Because the developer doesn't own the copyright to the engine?

    It's unfortunate that this model really only works for large developers serving broad markets like gaming. Whereas if you're an indie developer writing image processing code for example, it is going to be hard to find infringers and harder to strongarm them into coughing up licensing fees. I expect this has the effect of keeping source code behind closed doors that would otherwise be public.

    I would phrase it "contracts" - which has the implication that if you violate the contract, you may be sued. Contracts are how just about everything is "enforced". I think that programmers tend to think that if something is required, we must have programmatic protections in place that ensure it actually happens. Most of the world does not work like that; they rely on contracts.

    They don't necessarily need to do a lawsuit. They could just shut down your UE subscription until you file the relevant proof of earnings.
    • tinco 12y ago
      You don't need the subscription to work with the engine, its a GitHub repository you can just locally clone.

  So a state-of-the-art graphics library, a critical component to your new, moderately successful video game, doesn't deserve 5% of the revenue?
  • SSLy 12y ago
    Not to mention this is much more than a 3D rendering middleware.
  • cwyers 12y ago
    Yeah, if you think you can write your own alternative to Unreal Engine for less than (revenue-$3000)*0.05 per quarter, then by all means, you should do that.

      Competion is a wonderful thing. I can't build a decent car for less than the cost of a low end BMW. But, there are plenty of other companies than can. So, the real question is what are the other options out there and I suspect there are few engines that can come close.
      • cwyers 12y ago
        iDTech is no longer licensed for third-party use; only Zenimax properties can use it. CryEngine is available -- they have a $10 a month subscription plan that is royaly-free, but you don't get source code access like you do with Unreal Engine here. (They offer seperate terms for source access.[1]) Unity exists, but I don't think it's in quite the same tier as Unreal (although for some projects that may not matter).

    Perhaps not, as a graphics programmer, rewriting the rendering system is comparatively simple, enjoyable, and perhaps not worth 5% of a moderately successful game. However, UE4 is much more than just a graphics library. I'd argue that it's editor alone is worth many times more than their rendering features. And IMO, it's trivially worth the 5% of revenue.

  Or, you know, pay the royalty you agreed to pay and stop being a thieving scum. I would think they have some sort of enforcing mechanism. It almost seems like the $3,000 limit is a signal of the cutoff when it starts becoming worthwhile to pursue scum buckets.

  Speaking as another developer, their terms sound incredibly fair.
