I remember I was rather disappointed with the region used in Black/White. If I remember right, the big deal about it was that it was supposed to be much more of an urban environment than the previous games. I was fully expecting the entire game to be a huge city. Instead of separate towns, we'd be visiting various districts and neighborhoods, each with a different type of setting. Maybe one "town" would be made up of the low-income housing area (The gym could be themed like a boxing club or something), while another "town" would be something similar to Times Square (A gym done up like a shopping mall or business). A third area would be based around Central Park (The "Gym" is an open-air setting only separated from everywhere else with those rope barriers used to guide lines of people), while yet another would be Coney Island. (An oversized tent where Gym battles are big spectacles with an audience and everything, like a circus) You know, something like that.
Instead, we got a single city with panoramic views as you walked around. I admit, it looked rather nice, but then the rest of the game felt like more of the same setting we'd gotten used to before.
