I dare say that it's better than the console games !
BTW I'm Furious Carpenter (see you once or twice in the city Marvel Warrior). I'm using Spidey (lvl 9 right now), Wolverine(lvl 5, only bought him yesterday though), Ms Marvel (lvl 10) and pretty much every other (Thing, Falcon and Cyclops, all lvl 6).
Today, I'll be buying other characters... don't know what to do... I want them all so I just can't choose between one at 1000 or 2 at 600... it's killing me !
EDIT : Just notice that you're in my friend list ^^
