From direct experience it's just fine to carefully, thoughtfully do gamedev coding with AI.

I've always wanted to get into game dev but never did for lack of time or sustained interest. I tried to slop together some ideas and mechanics that I've been toying around with in my head for years now. And llms have no concept for the nuance that goes into actual enjoyable mechanics. Maybe it's just me, because I never put the time in myself so I can't get the results out that I want.
