I'm in the process of evaluating Go-raylib for a fantasy console project in lieu of Love2D. The basic rationale is:
* I only need inner loop high performance - it's a fantasy console, and intentionally limited. It will have some C code, but I don't want to write a lot of it.
* I want the project to be easy to build with few external dependencies(raylib is tops at getting this right)
* I want static types and zero-indexing for the "OS layer" part, at least, since I have to build some original data structures for IDE functionality(e.g. there will be a text editor).
It was the last part that made me switch away from Lua, and then it was the first two that made me consider Go.
I think the problem is the ffi overhead to C from Go is really high, like, way higher than any comparable language, because of the segmented stack thing. I mean the nice thing about Love2d is that LuaJIT has the best ffi overhead when calling C.
