Well, now that I've put in a few hours, I can say that it's a lot of fun. Designing a costume is easy, but fun. The powers are pretty cool. The city looks nice and is fairly large. There's nice touches here and there to be found.
The advancement system seems alright and they have neat things like the ability to be or take a sidekick (this allows the sidekick to fight enemies tougher than they normally could handle as long as they are in proximity to their mentor).
There are areas that can only be entered by groups, so while you can do a fair amount solo, it's good to find and make a team.
That's the weakness, though. After spending a fair amount of time creating my character (who I happen to find pretty cool), I don't want to be running into people who design costumes to look naked and then name themselves "The Burning Crotch". Sigh. But if you can get a good team, it looks like it should be cool.
