Ultima is a huge motherfucker of a game. Sure, a lot of the towns are carbon copies of other towns, but because space was saved in this way the world itself feels vast and open when you're in the grit and the shit. Notice how they took continents and just spun them 90 degrees to further save space. Overall it was a brilliant tactic.
However, Ultima II on PC is still my favorite for some inexplicable reason.
