i'm surprised no one's mentioned Okami yet. that whole game is absolutely gorgeous. and, from what i've seen, The Journey is made up entirely of one big exceptional location.
also, i'd say that in both Mass Effect 1 and 2, the Normandy is beautifully designed. towards the end of the game both versions of the ship started to feel like home. a calm, quiet place to relax and talk to your crew. not to mention that both games had some pretty cool set-pieces (like that ship in 2 that had crashed and was perched precariously on a cliff).
