No.
For example, he didn't like Uncharted 2 very much, but that's just his taste. Not everyone likes the same kind of games, and he does point out some flaws in games I like. As much as I like Uncharted 2, Nathan Drake is not a very well developed character. I find him likeable enough, but he's kind of a shallow action hero - a casual Indiana Jones if you will.
He didn't like the First Mass Effect very much. I, personally, loved the game to bits, but that's just his taste. He found the inventory system far more of a pain to deal with than I did.
I also dislike games he has liked. I found inFamous to be.... decent but it got boring towards the end and the story was rubbish. He liked painkiller, and I thought that game was terrible. I also disliked No More Heroes, the only game I ever bought on his recommendation.
So it goes both ways, I like some games he dislikes, and I dislike some games he likes. That's normal, BECAUSE WE'RE TWO DIFFERENT PEOPLE. We are not going to like the same things!
