The largest "game" that I'm aware of is a piece of closed source CAD software [0]. They've been thrilled with the performance and ergonomics of the code, although they're relying on egui [1] for the UI. As to scale, they crunch absolutely absurd amounts of data, seem to have an impressive amount of functionality, and are regularly hiring new folks from the community onto their team.
