Metaheroes.

It's a game inspired by comics, and it's great. Yes, it's invite only, but if you TDM and enjoy it, there are often invites floating out there. I have less of a pitch for that one to throw out, but it's tons of fun, has monthly events or player plot events, and characters that don't inherently have powers get some on arrival, along with the choice to join the heroes, villains, or go be unaffiliated. It's pretty fun. AC is a 'report on what character was doing' style.
