That's why, the first time I saw Bevy and Amathyst, I had an immediate "they're doing it wront$ reaction. IMHO, to be a true game engine in the modern sense, instead of merely a game framework, your engine needs to be a precompiled, standalone executable in a systems language that picks up, loads, and executes game scripts, data files, and assets that are totally separate from the engine itself and written in higher level languages. You don't want to be writing everything in a rigid systems language and especially don't want to have to compile your game logic and your engine together and then link them as if the engine were a library. That's why I'm (very slowly) feeling out what a proper game engine in Rust might be like with https://github.com/alexispurslane/embryo-engine. It will take me some time, since I have to learn real time computer graphics and a lot about game engines, but I've got the books, I've made a lot of progress in learning them, and the engine design and architecture is coming together very well in my big black notebook, so if you're interested, give the repo a watch ;)
I'm debating between embeddable common lisp (to satisfy my hacker impulses) or C# for the scripting language. I have figured out, I think, how I'll embed C# in Rust down to some pretty detailed steps, involving a two stage process, but .NET is so heavy I'm worried if it'll be worth it. I'd love input!
