Square should solve this problem and make a new Dissidia for the PSN. Everyone gets their FF represented.
Yeah Sephiroth is pretty cool. He is one of the greatest villains of all time. I would enjoy playing as him too. But Sephiroth still wasn't iconic as Cloud. Also, think of how hard Sephiroth is to beat. He would be very overpowered in a game like PSASBR because of his sword! He would have the greatest range in the entire game with his sword alone. Haha
It's called balancing. Kratos would be overpowered in a game like this but he's balanced to this game's world, not his own. The most people will have to deal with is Tiers.
And I find it hard to believe that Sephiroth with Masamune would have further reach than a 'gun'.
People keep bringing up Cloud, Sephiroth, Lightning, Zidane, Squall and them, but i have yet to hear anybody mention someone who, in my opinion, is one of the greatest characters ever. Auron, from FFX. Anybody at all agree with me that he'd be an epic rep?
No matter who represents FF, superbot is going to get a lot of hate XD they should play it safe and not include anyone
