Realistic expectations or not, one thing is certain - we need more games based purely on cooperation, including MMOs. I once thought of online game with community features (not quite a MMO, but not just multiplayer either) which would rely on players helping each other out with missions. For example, if a player gets cornered by enemies, he can send out an SOS signal. Everyone in his immideate vicinity will be notified, as will the players on his friends list (if they are currently running the game). Someone then can fly in a Big Damn Gunship and airlift that player out of a sticky situation. For that the rescuer recieves a positive reputation, which provides some kind of advantage.
This is just a general outline of an implausible concept, so please don't hate on me.
