....Actually this is more based on D-District rather than the Missile Base. Controlling Selphie is incredibly brief (you are forced into one fight with her as your only party member, but that's it).
Cosplay Crisis does have several 'replicated' areas (Miehlebin, the Ragnarok) which is for nostalgia/story reasons. Banora derives inspiration from various levels but is more or less it's own.
