It's simple. If it's a good game, with good reviews, and the vast majority of people like it... he'll do nothing but criticize the game.
If it's a bad/mediocre game, with poor reviews, and a lot of criticism from players... he'll do nothing but extoll its virtues.
I don't have any real issue with the top 100 played. For the majority of them, I can see the reasons why, even if I wouldn't play it.
But then again, I haven't returned 1/4+ of the games on the list like someone else might have.
