I don't think I can compare FFX and FFXII. Both games are amazing, but very different from each other. I am enjoying FFXII a lot though. The battle system is a little bit like a MMORPG. My favorite characters are all the girls Fran, Penelo, and Ashe. They are all really good. I usually play with two different parties.

Party One:
Fran
Basch
Vaan

Party two:
Ashe
Balthier
Penelo

but if I get into a real bind I use Fran, Ashe, and Penelo as my party. Those three together own. My characters are all lvl 19.

I've got 24 hours on the game so far, but 8 of it is probably time where I left the game on.
