Use of GC in Nim is up to you -- you can malloc/free as you please if you want and avoid it altogether. I'm not sure to what extent you can/can't make use of the standard library if you avoid GC, but even if you lessen your restrictions and use it a little bit, it's a highly tuneable/controllable and understandable GC including support for swapping out entirely different GC algorithms. Professional game development as in AAA studios? Yeah, probably not, but more for the tooling alone than whatever language any particular studio happens to use. Professional indie game development? It's ready, even though it's not at 1.0 yet. Indie devs deal with big breaking upgrades to their frameworks (Unity, Corona, etc.) all the time, it's annoying but not a deal-breaker if the language gets those sometimes too.
