Actually to me Yahtzee sounded extremely bias. It seemed he was expecting something along the lines of The Sims, like most people who for some reason had crazy expectations for the game, and didn't get exactly what they imagined. Sure the game did not live up the hype it generated, but I sure had fun playing through the beginning stages of the game and the space age was the best part. Is it a ground breaking evolution in gaming.... no, but the game itself is not as bad as I think Yahtzee makes it out to be.
Then again, like Angry Video Game Nerd, he rarely ever praises a game because that would be boring. You get more hits when you point out the fallacies of a game and do it a hilarious way at the same time. I really don't trust any one reviewer and always take in serious number of reviews before making any time of decision, and Yahtzee is not excluded from that.
But that is just my opinion
