pwn3d, maybe there's recycled material because it's a sequel to kh1. i bet there would be complaints of there being little connection between the first and second games if there was no recycled material. the worlds are larger, by the way. you play multiple episodes for each world.
one world in kh1 = one episode in kh2
the worlds are larger.
one world in kh1 = one episode in kh2
