Single Campaign, Multiple Groups

For food of thought and history of such experiences if you have any, have you ever played in a campaign with multiple groups, even with at least 2, I tend to call this MMO due to the MMORPG genre, of course that doesn't make as much sense due to online, unless you are playing the game via chat.



I would think that the superhero genre would be a good fit because the plots are very episodic and tend to be battles. The Marvel universes does this with teams of heroes have there adventures and then cross paths to enter an epic adventure.
