Calling an MMORPG a dissapointment will surely cause many exasperated sighs. However, the sad truth is that the plethora of MMOs severely lack a valid comic book/superhero-themed game. City of Heroes got the ball rolling, but it was damned into lawsuit hell as copyrighted characters sprung up nearly every week. Champions Online appeared to amend that malady by allowing players to have complete creative control on how their characters looked.
Lamentably, the game suffered from sloppy inventory management alongside an immense amount of homogenization with the various superpowers; selecting an ability was a futile activity, as everything dealt the same amount of damage, only with different types. In the end, Champions Online is a valiant effort on the part of the developers, but not quite enough.
