On Steam I found this curator who rates all/only games made with Godot.
I personally don’t like reviews that tell you nothing useful about games and wish there was a tag for the game engine used, but If you ever wondered what games made with Godot are out there, you find plenty (1755 at the moment) of them here:
EDIT: Just noticed that it says “maintained by Godot contributors”.
Sorry to break your heart, but this curator is not accurate at all. One of the games it recommends is my first game I released - Bedroom Battlegrounds, which was made in Unity. I have no idea how they assumed it’s Godot, they never asked me about it, just put it up there “by the hunch” I guess?
