1: Where's the "I hate this game because I genuinely think it's a piece of shit that isn't worth playing" option? Because that's what I fall under. If I hate on a game it's because I genuinely think it's so bad the pirates got ripped off and deserve their money back. If that coincides with a popular game, then so be it. I don't care.
For example, I think MW2 fucking sucked donkey dicks. I came to that conclusion after A: Getting a KDR above 1:1 in multiplayer, where my normal score in such a game is about 1 kill to four or five deaths, and B: I realized the campaign was a bag of testicles about the time I ramped the snowmobile over the ravine. That may have been awesome but it didn't fit, would have been much better placed in, say, Grand Theft Auto, and then there was No Russian, which although I found it quite amusing, again seemed out of place. That was only there for shock value, it added fuck all to the plot.
2: Don't be hatin' on the cynical snobs. TB and Yahtzee are fuckin' hilarious.
3: Of the three cynical snobs you listed only Yahtzee does SP only. TotalBiscuit not only plays multiplayer, but casts E-sports. Usually Starcraft tournies but I'm sure he does others too. Yogscast casts e-sports as well, and they, again, play multiplayer.
