Final Fantasy X - 2 . . . .

To buy or not to buy.

Ok, this may sound stupid, but i have not been a fan of the FF series since 7 and 8. I need a new FF game cause i miss playing them. I will not play X because those gay puzzles are so annoying, and titus is a total chump. The story in X is good, but it gives the game no replay value since the main character evaporates at the end. Why do i want to get X-2 then?

I hear the gave has a totally new battle system with "active" and "wait" modes and that you can change your characters role in the fight (i.e. go from a majik oriented character like Aeris to a muscle head like Barret).

What do y'all think?
