Far Cry 4 wowed me when I first played it, you're sort of in a valley within 2 mountain ranges, and those mountains being really detailed helped with the sense of scale.
Also, I'll mention Battlefield 4 because it will probably be overlooked. Both single player levels and the bigger multiplayer maps have awesome scale.
