Nope. For all the years I've been gaming, I figured out pretty early on that all games will have flaws. While I notice them, unless they make the game completely unplayable (and I play games for the game part not the story, even JRPG's. If it has a great story, that's just icing on the cake. Bad gameplay will make me not care about a story even if it's the greatest of all time). But for all of Yahtzees nitpicking, he picks and chooses what games he sees the flaws in, basically it's like this- if it's from his beloved Valve or Stealth games he overlooks the flaws that he complains about in say Halo because he likes those types of games and doesn't like Halo (just using that as an example).
I've seen him be called a professional troll, but I'm thinking that he's more of a professional hipster with a hatred for anything that is mainstream (because like it or not, Half Life 1&2 aren't as mainstream as Halo or COD) or he can't admit to love in an ironic sense (the Dizzy games anyone?).
