I agree with most of his awards. And I think the "turd in a turd" award should be given out annually by every media outlet. I do have one gripe, however, about his assessments.
I realize this might go better as a response to the review of Prince of Persia, but I kind of liked the ending of that game... it went along wonderfully with the Prince's cavalier, jerk-off attitude. And the fact that I knew he was going to behave that way even before the "fake" ending sequence serves as strong evidence that his behavior (while stupid) was in-character. And if memory serves me correctly, Yahtzee liked the Prince. Maybe it's because they're both sarcastic, cynical dicks. Alternatively, maybe it's the crazy scarves on his head... a poor replacement for a bowler, I know, but Zoroastrianism is a weird religion.
As for him behaving badly for the benefit of a character "no one likes," I haven't heard anyone else complain about that character. In fact, most people I've read reviews of or spoken to actually liked the character a lot. She's no Alex from HL2, but who is?
As for her schizophrenic behavior, I think the unusual circumstances she's found herself in paired with her dual X chromosomes give her a pass to act a bit emotionally from time to time, don't you?
