A great game for any Xbox 360 person who enjoys MMORPG's. This is one of the best. I've played on the PS2 for a couple of years and recently bought it for my 360.
Graphically - the game looks MUCH better than the PS2 version. Other than that - it's the same game that it was when it came out a few years back with some minor tweaks.
You can voice chat via - Xbox Live and then there is the Achievements but it's not all that great. I must say that Final Fantasy's Achievements will definitely be hard to achieve - well - not hard - but will take alot of time to attain unless you've been playing for some time.
This is a great game w/ lots to do and many people to meet. All the different jobs bring a different experience. When I am feeling like going on a rampage and want to hit hard w/ magic - I pull out my Black Mage, or when I want to shoot stuff w/ bow and arrow or even a gun - I play Ranger! Summoner is a fun job as you get to call somewhat powerful avatars to your side to buff your teammates as well as attack monsters you are fighting.
You can play however you want. The game is totally open ended. You can even be a gardener, blacksmith, cook, whatever you want.
Once you get through the rough start, this is a great game. I give it an A- and the - is just for the hell of it!
