I think a Jenova battle in the Mansion basement instead of the boat might be a really good one.

Then again, I guess a cargo ship would allow for more room. Maybe the Shinra lab could be expanded in size like the one in the Shinra building.


I think some kind of flashback battle featuring a younger tifa/cloud getting thoroughly hammered by Seph could also be some fun, along with a bunch of Tifa "i dont remember any of this" stuff.
