I love snow too!! In shooters my favorite maps are always the snow maps. But I love so many other environments.
The standard Medieval Europe setting of most WRPGs and some strategy games like Age of Empires, Mount & Blade.
Castles and ruins and other historical settings. Just pretend a dungeon crawler in ancient Egyptian pyramids. Anything. There's so much. Uncharted 1 and 2 have very nice varied locations with attachment to historical buildings, objects and religion.
Deserts. (Red Dead, Quake Wars and Bad Company 2 come to mind)
Hell. (Dante's Inferno, the Oblivion realm in Oblivion)
Forests (countless of games thankfully). I love foliage!!!
The space sci-fi indoor settings.
WW2. Still love it. The trenches, the war machines, everything.
