The SR2 fans seem to say that SR3 is a terrible game that completly ruined the series
I think part of the reason I wouldn't be able to get into Sleeping Dogs is that I had spend som much time in SR3 (which is the first game of this type to draw me in since Vice City).
If you ever need a coop partner, you can find me under the same nickname on steam.
Especially when Saints Row 4 comes out soon.
And it does come better than that. Wait 'till you do ensurance fraud challenges: launching yourself in front of cars, so you can get run over and tossed around to claim insurance.
