a community quest design contest? Members of the community can design and submit their ideas. Only the winner is guaranttee to have their quest included in the game but other entries may be implemented too.
Of course, this might be more headache than it's worth but fun for everyone else.
i could remind you of M&M IV where after all the carping Scorpia did she got entered into the game. Looking like a 300lb denizen of a street corner light post complete with pearls and fishnet stockings.
being as in RL she's a powerful adventurer, they gave here 1 or less hit points so just swinging at the monster killed her.
