I just found this game today, It looks really fun. I was always wanting to play City of Heros but never got into it, This game looks MUCH more expansive and exciting and much more customizable with the character you wish to play.
Even the PVP (which is very wow similar 'instanced fight zones') looks to be pretty fun.
I dont know alot about this yet, I applied for the beta and am hoping to try it soon.
Came to see if anyone else here might know more about it or have a beta invite and tried it yet :)
