*thinks of something to speculate about*
Ooh, how about this? So far, every gen has had kind of a Ghost place; Kanto (had) Pkmn Tower, Johto had its towers (most noteable Burned and Bell), Hoenn had Mt. Pyre (best one so far, according to me), Sinnoh had that little worthless tower at route two-hundred-whatever, and the Gateu.
Wht will next gen have?
Personally, I've been hoping for a while for a graveyard forest. One of Europe's biggest graveyards, The Forest Graveyard in Sweden (that I happen to live quite close to) comes to mind. That'd be pretty interesting, I think. A huge forest with mist, maybe even some caves, all filled with Ghost, Dark and Grass Pkmn.. :3
Oh, and some graves where certain Pkmn evolve.. *CoughGhostEeveelutionCough*
Anyays, what do ya sy about that? This region looks very urban from what we've seen, but we've virtually seen nothing. So I'm getting my hopes up :D
