Saints Row is a co-op game only, IMO, like Borderlands. SR4 looks to be nutty and off the wall, but I think they made it that way knowing many people will co-op it (which I plan to do starting tonight).
You and a buddy running around naked with a mexican wrestling mask on, flying in the air and throwing cars at bag guys with your mind is just simply a fun time. Too many games take themselves seriously these days and Saints Row is a nice refreshing break from that, IMO.
