Several:
The Medal of Honor: Warfighter "ha!ha!ha!"/Doom 3 review retrospective. He pointed that despite the flaws of Doom 3, it's still head and shoulders above COD, or any other contemporary shooter that tried to play follow the leader during the seventh generation. It really goes to show how shooters or other game of different genres had fallen by trying to attract a crowd that had no interests in their franchises to begin with.
Similarly, the whole FF XIII gets good in 20 hours made quit the altogether. I wasn't having any fun at the 10th hour.
His review of Wet stuck with me because he was right in that just making your female character a "bad ass" doesn't make her fun or a well written character. Rubi is an unlikable *****, whose just a knock off of Revy (another character I equally despise) from Black Lagoon. The same applies to male characters as well, but Wet really stuck out. Plus, I played the demo and wasn't having any fun; the QTES being one of the worst implementations I've ever seen.
The last one, Mad World, stuck with me for negative reasons. I consider it one of his worst reviews, as the episode itself wasn't a review. Most people agreed with me, because a lot of them carried the same sentiment in the comments section.
Yahtzee was just straight up console bashing for the majority of the episode. He had a point about having blood or gore in your game doesn't make it mature, but he missed the point, because Mad World was good dumb fun no different from Doom or No More Heroes There was more going on with No More Heroes, but Mad World had a point as well. And Mad World had a great story (which he leaves out of the review); especially if an astute player is paying very close attention. There are flaws, the traps and level layouts get less creative by the time you reach the 4th stage, but it's still a great game. The motion controls do work with the QTEsWhenever you see a vertical swipe gesture, never turn the Wiimote side ways, it'll read your motion as a horizontal gesture. This will mess up or make you fail a QTE , but Yahtzee could never figure them out. I was able to figure this out halfway into my first playthrough. What was his excuse?
