It is if you're writing a game from scratch, without need to deeply integrate with something like Unreal Engine.

I used to write games in plain C, and nowadays I'd definitely use Rust for them.

There is a small Rust games community and a couple of engines/frameworks: https://lib.rs/game-engines

One thing with Rust is that it pretty much requires use of entity-component-system. It's the best practice for real-world games anyway, but people who write their first game are surprised they can't just "wing it" with some ad-hoc OOP.
