The only MMO's you really need to worry about are ps3 ones: DC Universe online (which is ok), Defiance (also ok but gets boring fast), Freerealms..., PS home... the secret world (not released yet i think), The Agency (also not released probably not going to be eaither)

& i can tell you FFXIV ARR is better than all of them. well that is if you like RPG games, if you like shooter mmo's then defiance is your game.
