This is great, because Unreal is a C++ project that's not so easy to just Rewrite In Rust.
It's also nice it uses bevy's ECS. It's made to fit Rust's type system and borrow checking model, and is highly parallel. It's really awesome how easy it is to distribute work across cores with it, without risk of heisenbugs thanks to Rust's data-race-safety guarantees.
I know game development sees traditional software best practices as not applicable to them, but then games struggle with showstopping bugs and single-core performance bottlenecks. I hope someone will bet that Rust, despite being stricter and seemingly slower to iterate with, can be a net benefit from lower defect rates. Rust users outside of game dev praise the "if it compiles, it's usually correct", and that junior devs can be told not to write unsafe code, so they can't cause UB and memory corruption.
