^I'm totally fine with FF characters showing up, so long as they stick to the main story instead of rehashing their own dumb conflicts. I don't doubt that people like Squall or Aerith might make appearances as kids or teenagers.
The only way I'd be happy with Sephiroth showing up is if the game briefly shows the origin of his and Cloud's enmity, and that origin is something stupid like Cloud walking home from school while eating a sno-cone and Sephiroth comes along and slaps it out of his hand, and then takes his lunch money. That would be fitting.
:thumbup: Oh yeah, that would be befitting!
