Seems like a huge chunk is missing there, these mostly seem to me like a bunch of smaller reusable components with nothing really tying it together.

Makes sense, they probably don’t want to leak _the_ secret sauce driving the game itself.

I saw some eve-specific logic in Destiny repo, like warp enter condition and warp velocity math, or entity visibility between grids.

(Also, it’s full of std::(unordered_)map/set. Surprised they didn’t try squeeze some more perf there.)

If there was ever a game where the secret sauce doesn't have anything at all to do with the code, Eve has got to be it. They could probably release every single thing including all of the assets, complete buildable client and server code, etc and I doubt it would hurt the Eve at all.

But they announced it as if they are releasing a game engine? This is just bits and pieces of one with major missing pieces so I'm not sure what the point was with that. I guess its more to help modding or they are yet to release everything they wanted.
