You mean, the locations actually look different between versions? That's a first. And Black City is starting to sound appealing.As ashgirl said, the games diverge a little more this time as opposed to previous generations with version-specific locations. Black has Black City--a dark, industrial place that has trainer battles and evolutionary items for sale--and the city which holds the final Gym (Opelucid City) is sleek and technologically advanced. A man named Drayden is the Gym Leader here.
White has White Forest where Black City would be, and it's a huge forest where wild Pokemon and items can be found. In White, Opelucid City takes on a more ancient appearance (it still resembles a city, but with stone where there would be steel). In White, Iris is the Leader in Opelucid City.
But for the stories... they're for the most part the same, from what I understand. It's only the locations themselves that are different between versions. Team Plasma doesn't act any differently, I believe. The only characters that I know change roles (excluding some trainers which offer either Rotation Battles in Black or Triple Battles in White) are Iris and Drayden, as the one that you don't challenge does something different in the game.
I may just pick it up during the Summer time...
That's gotta suck. But, you could always just Wi-Fi battle them, right? Or, is there something preventing you from doing that?Yeah. According to Serebii, there is one (1) Rotation Battle in White, and one (1) triple battle in Black.
Which makes choosing White very hard for me.
