Well maybe you consider PSO the same as FFXI/V but I don't. If that's the definition of an MMO, we need another definition to separate the likes of PSO and Monster Hunter.

Although I think a good definition for games like these are that they are Online RPG's, but that inevitably is in conflict with your definition of an MMO.
