Few thoughts,
It's pretty much WoW as a single player game, story's good but I hate all the running if I'm not in the mood for it. Graphically it's great, so is the Voice Acting, you really can't do much better in the PS2, I'm totally impressed by the level of background detail in the cities and such.
Gambits are fairly worthless, I only have two set up for all my characters (attack leader's target and heal if Allies HP<30%) and never have to manage anything except in boss combat. Not really sure why you need 10 slots. Summons are cool but don't care for mistings, not that cool looking nor that fun to time.
I like the license board but LP are too easy to get, I'm only about level 24 and all my characters have over half their boards filled up in the abilities section, haven't bothered much with weapon's or armor since there's no point in buying them until you actually get the item.
It's a fun game but now I've got it, Zelda and NWN 2 to play (my roommate bought it but can't run it on his PC) so I don't even know what to do with my game time.
