There's this game series called Dragon Quest. You may have heard of it. Okay, tongue-in-cheek attitude aside, it's true - the upcoming Dragon Quest X will have online co-op. Players will be able to form parties to go forth and quest for dragons. Yes, it sounds like it'll basically be an MMO. It also has a somewhat ridiculously long subtitle: Dragon Quest X: Mezameshi Itsutsu no Shuzoku Online (which translates to Waking of the Five Tribes Online).
