"It's gettin' it's gettin' it's gettin' kinda hectic" - The Power, Snap
I do not play play City of Heroe's/City of Villains much (Ardua does though!). I really like the concept of the game, but I just cannot bring myself to do the PvE grind to the level cap. Not the games fault, just a phase I am going through.
I could not help take interest in the upcoming content release, Issue 13: Architect. The gist of it is:
"Using an intuitive interface similar to the game’s detailed Character Creator, players can create missions from the ground up. Players will determine details ranging from environments, mission objectives, and enemies, to written fiction and character dialogue, giving their stories nearly infinite depth and personalisation."
It is basically player made quests. It is one of the most awesome things I have seen go into a major MMO. There are many creative folks who play MMO's who will take this kind of tool and run with it.
This only other similar system I know of was the SWG Storyteller system. It is very neat in its own right, but was not friendly towards other people participating as quests. This looks like a leap ahead, which is great to hear. Hopefully this will advance user-created content in the MMO industry.
