Use of GC in Nim is up to you -- you can malloc&#x2F;free as you please if you want and avoid it altogether. I&#x27;m not sure to what extent you can&#x2F;can&#x27;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&#x27;s a highly tuneable&#x2F;controllable and understandable GC including support for swapping out entirely different GC algorithms.<p>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&#x27;s ready, even though it&#x27;s not at 1.0 yet. Indie devs deal with big breaking upgrades to their frameworks (Unity, Corona, etc.) all the time, it&#x27;s annoying but not a deal-breaker if the language gets those sometimes too.
