Good game, Really cheap. Some helpful tips/advice/information:
Monthly subscription of £8.99.
You need to enter your credit card to get your free month.
After free month £8.99 will be taken. (so remember to cancel if you dont wanna play anymore.)
Keyboard or chat pad needed to talk to everyone as no voice chat.
Hours needed to install game and get update.
7GB+ needed on Xbox hard drive for updates.
Alot of grinding involved at the start. (but only the start)
Really good game though, Graphics arn't amazing but once you get into it, its really good :) You dont even need to be a Final Fantasy fan to play! Also the PlayOnline interface is cool. :D
