I liked it. Not as much as any of the others I played but I thought it was fun. I like the speed the game runs at and how your characters aren't all lined up in battle but scattered and move around. The only thing I thought shouldve been done better in the game was this.
I would have liked more of the towns and places you visited again to be different. The only place different was Kilika and the Fayth Wall on Gagazet. You'd think after two years without Sin, tech wouldve boomed. Another thing i wouldve liked is the characters that reapeared from X to have different clothes. Especially Wakka and Lulu. Apart from that the game was fine.
(Thats from an old thread I posted in)
BG-57 has the right idea though, people compare it to X because its a sequel. Thus it gets crap.
