Nimbasa City is a city north of Route 4 and the Desert Resort. West is Route 5, east is Route 16. It's the second biggest city in Unova, second only to Castelia City. It's interesting to note that Castelia serves as the buisness center in Unova, Nimbasa is the opposite, being full of fun games and stuff to do.
