Amazon going all-in, releasing their own "triple-A" game engine, absolutely free to the public. Built off of the foundation of CryEngine, and tailored for deep integration with Amazon Web Services and Twitch. The fact that you can use Lumberyard to build a game, then release that game commercially, without any payment to Amazon, is very interesting. The are counting on a lot of developers taking advantage of AWS, of course, but what does this mean for the rest of the game engine field? When will Adobe, Apple, and Wal-Mart release their 3D game engines?
