It's a bit of a weird edge-case, but the very popular Battlefield 6 is partially a Godot game. It's an odd hybrid of a proprietary in-house engine with Godot grafted onto it, which serves as a public-facing SDK for players to build their own content. I know that's not exactly what you meant but it is an interesting application in a major AAA title.
