Why would you think that? All of the game developers I've met don't really view themselves as separate from traditional software best practices, just that there's a lot more involved in making a game than people are ever really aware of. They're also among some of the most talented programmers, the stuff they have to come up with is insanity sometimes, so it's certainly not about them not caring about best practices. Games aren't struggling because they're written in Unreal's flavor of C++ (or whatever other currently existing engines and their respective languages), there are insane deadlines always being pushed. There is never enough time and never enough money. Neither of these problems are solved with Rust, at least not to a substantial degree.
