The same goes for everything in ME1 that isn't the Citadel (and even that is nothing compared to, say, Athlaka in BG2). Both games are SUPAR STREAMLINED in that regard.
Off the top of my head: Kakariko Village, Nibelheim, Arni Village, Guldove, the peasant village from Resident Evil 4, and the fishing village whose name I can't remember from Baten Kaitos.
Come to think of it, a lot of my favorite locales from games have been cities.
There is a particular town in White Knight Chronicles that I love, at least conceptually; but given the recent release of II, I don't want to spoil it for anyone.
