So I've been playing around in the Open Beta for Champions Online, and I have to say, if you are into MMOs you should check this game out. It's pure fun, and even as horribly broken over-the-top as it currently is, that can be excused because it's intensely fun. The character creation options are ludicrously in depth allowing you to play pretty much anythign you want, both from a look standpoint and from a build standpoint.
I've been pogoing around as Commander Keen for the past week and it's been the most fun I've had with an MMO since the old days of Vanilla raiding when I used to have the time and desire to do that sort of thing. It's definitely worth a look for anyone seriously into MMOs.
