"In multiplayer mode, the player's class greatly influences lifespan. Five character classes can be picked including Warrior, Archer, White Mage, Black Mage, and a support class. Each has specific roles to be fulfilled in the multiplayer mode.
The Warrior is the typical melee fighter type. The Black Mage and Archer fight from long range. The Archer uses a bow and the Black Mage fires offensive magic such as Fire, Blizzard, and Thunder. The White Mage is used to manage the party's health, status, and the support class is helpful for creating magic orbs that allow magic users to cast their spells. For example, if fire were to be cast, it would require one orb that corresponds to fire. Once the fire spell has been used, the orb will disappear.
There is also a Multiplayer mode via Nintendo Wi-Fi Connection, this is used to trade customized moogles the player creates throughout the single player mode."-Wikipedia
Yeah, I'm getting this game for Easter, even though the co-op will be multicard only.
