What I can't stand are the 'fans' obsessed with FFVII despite never having played it. I mean the type of people who say how awesome Cloud and Sephiroth are because they're so dark and have big swords. Those kind of fans don't see past the game's appearance to appreciate the amazing plot, the depth, the character development, and the impact it has on its player. Hell, if you asked them who Cait Sith is, they'd likely say "Who?" and asking about Aerith would prompt an instant "LOLSHEDIES".
I love FFVI and FFVII. Imagine the horror if FFVI got as market-y as VII. The inevitable FFVI DS remake will likely be as far as VI's development will go anyway, but considering FFIV got a sequel... Anyway, FFVI DS would, no, will be awesome.
Holy crap this is a Dissidia thread! Whoops.
Terra would work well since she has her Esper form (considering other characters' transformation abilities in Dissidia).
