More than just a sequel to Final Fantasy XI, this is a whole new game with a very different approach to online gaming. Playing on your own is now just as rewarding as battling in groups and your character's progression and growth is achieved by using and refining your existing skills, rather than just earning general experience points.
Likewise you can change jobs simply by taking up a different weapon or item, from sword to blacksmith's hammer, although specialising in the game's four disciplines (war, magic, land and hand) will always give you an advantage. The end result is a more accessible and varied experience than any other online game and the most exciting Final Fantasy yet.
