Halo - Very original atmosphere and overall immersion factor that I still to this day has not been matched by another shooter.
Splinter Cell (original trilogy) - Very authentic spy & espionage atmosphere.
FEAR - Big fan of abandoned factories / office building setting and secret facilities in general. FEAR was a very eery game with amazing horror scenes.
Stalker - Very authentic and creepy atmosphere.
Alan Wake - Big fan of shows like Twin Peaks, Millennium and X Files. Nicely designed settings.
Assassins Creed games, especially AC2 and Brotherhood. City of Venice is probably my favorite historic setting ever seen in a video game.
