Too hard to say because there are so many with strong atmosphere, who left a strong impression due to their special atmosphere.
I love when a game has a certain atmosphere that is hard to describe in words but you just feel it, and most great games do.
Dragon Age Origins had great atmosphere.
Oblivion had, obviously. It's the best game of all time.
Dark Souls has
Dead Space had a special atmosphere.
Red Dead
Vanquish
Hunted: The Demon's Forge
etc etc
