Halo Reach
Assassins Creed Series (Landscape, mostly)
Fallout 3
Oblivion, especially the Shivering Isles
Final Fantasy XIII (Let's all just admit here, it sucked as a game, but fucking owned as a movie/cutscene behemoth)
Mass Effect Series, especially the Citadel when you first get to that cutscene approaching it, and the various planets groundside in ME2. Fucking beauties.
