There's really nothing to crackdown except orb hunting though. Everything else is so poorly handled that it resulted in a boring game. At least in prototype you get some of the crazy movements and skills that are in Crackdown but you get an open world game that's a bit better made overall.
Infamous 1 though is just a snoozefest. They thought they could sneak in a mediocre 3rd person shooter and hide it under "superpowers" and the most mundane climbing mechanic ever.
Now every time I see you I read your tag and not your post, heh.
