I think the real issue here is with the training speed. Presumably a GPU is required to run the game, but is it restricted to just NVIDIA GPUs/a subset of those? I don’t know of any such libraries offhand and my guess would be that’s because the size of the library generally matters less if there’s a requirement to have a powerful GPU.
