I am just saying it does not need to be anything like MMORPG to be MMO. I just break the word MMO down to its basic meaning. Massive Multiplayer Online. This tells me that to be MMO I need many many players online playing my game. Of course in an PvP or Co-op environment. It just logically makes sense to me. It would then be up to the developers or Publishers to put an MMO tag in the title or not.
