Because people just wanna hate, but then they want to compare that Sleeping Dogs is better than Grand Theft Auto franchise. I'm willing to bet these people have never played San Andreas and will easily turn coats once V comes out.
I love Rockstar, but I'm not willing to do anything to accumulate the 17 entries per day just to get a chance to win this. I simply try to avoid supporting Gamestop as much as I possibly can.
