Hmm, as long as it's not more expensive than CoX, I'll be willing to join into it. Though, it angers me that they aren't just including villains into the game.
I mean, the idea and necessary creativity is already out there, why not put it in now.

Now an expansion I'd like to see is City of Civ-err...Civilians Online. I mean imagine it, you're a civilian being hassled constantly by the villains and you have no super powers. I mean, the mission types write themselves. You can play the lawyer class and try to sue villains and then avoid being killed/kidnapped for a period of time and boom, finish the mission.
