I think you are correct. I work in game dev. Almost all code is in C/C++ (with some in Python and C#).

LLMs are nothing more than rubber ducking in game dev. The code they generate is often useful as a starting point or to lighten the mood because it's so bad you get a laugh. Beyond that it's broadly useless.

I put this down to the relatively small number of people who work in game dev resulting in relatively small number of blogs from which to "learn" game dev.

Game Dev is a conservative industry with a lot of magic sauce hidden inside companies for VERY good reasons.
