Hmmm.. Nope, not really, occasionally I'll agree with certain things, he just has more hilarious ways of putting it than I do. I've bought and still enjoy several games he didn't have anything good to say about (not that he frequently has anything good to say about anything), even if he blasted the entire Armored Core series (my fave gaming series personally) to bits I'd still say "lol, no, dont agree with you,"
Letting a single opinion among the many thousands out there sway you isn't enough, you have to like it or hate it yourself. Not everyone has the same tastes even if many games are made for large audiences, its often the smaller groups with specific tastes that get left out since its not as profitable to work toward their needs either.
Yahtzee does a great job of putting his views across in a way that is funny and, for the most part, inoffensive if you take it all with a pinch of salt. I'd be glad to see what he could come up with for a lot of my favourite games xD not that I expect he will.
