Whoever solves this problem will make the mmo I want to play. I would cite a game like Eve Online as kind of a prototype because the game world is shaped by player actions to a certain degree. Of course this is also what makes it hard to get started.

I really want an mmo where everything is provided for you but the nature of the game itself causes players to create quests or mission for you to go on because they can't do it them self. It's hard to even describe the kind of game I want but I will know it when I see it.

I hate how now mmo's seem to be simply setting the same mechanics in a different locale and calling it new. MMOs need to get back to their roots and make something that is what an MMO should be instead of an action mmo, or a shooter mmo, or an urban warfare mmo. Those things are fun too but I want an mmo that focuses more on creating an immersive, persistent world.
