No Superhero MMO except City of Heros!
CoH/CoV is closed down now, unfortunately. Champions Online is a joke, but that was to be expected when Jack Emmert and crew left CoH/CoV, and with it most of the actual talent that Cryptic Studios had. For me that only leaves DCUO, but that's ok; Marvel burned their bridges with me, so I switched over to DC a few months back. Yeah, it's run by SOE, but at least you can make up your own character, unlike Marvel's game.
