Deep storyline, fun battle system. Cool moves. I wish I could do that.
Gameplay involves many twists, each more fun than the last. It is usually easy, unless you are on hard mode. Then you have to think your attacks out.
The graphics are awesome. Fire and explosions, old villains and new weird villains, Heartless and Nobodies, bringing FFVIII and FFX2 into the picture. My favorite character...Auron.
The only thing different that really sucks is that the Olympus Coliseum Tournaments no longer award experience. However, it is easier to hit level 99 outside Tournaments.
Definitely worth the money you pay, if you keep on playing. Lots of addicting play here.
