Crystal _could be_ for game developers; there's large green pastures left almost entirely untouched for a language to disrupt it. You see a few niche languages make inroads, like Haxe, but I expect something could really effect change.

The key is to be as fast as possible, as memory light as possible, and able to produce and speak to C ABI.

Nim and Lua are in that pasture. Being fast, memory light, and the C interop are the key features of Lua.

Lua yes, and since the 90s, but Nim? I've not seen that yet. What games use it?

There's integration in Unreal Engine for Nim.

I'm not saying it's widespread, but the language features put it in that field.

Jon Blow's (developer of "The Witness") Jai is worth mentioning in that context (not released, though).
