The Mass effect review, though he also mentions he generally doesn't like RPG's.
I didn't think Painkiller was really that great. I bought it after his review, but still haven't finished it because I keep losing interest. Ironically, I loved Serious Sam.
I also disagree with him on the ending to COD4, being I thought it was appropriately tragic(or bittersweet) and it hardly "comes out of nowhere". I mean, you are being chased by the guys entire army in the last level, and the game already shows it's willingness to show bad things happening to the protagonists(i.e. the nuke).
Really, the point where I listen to him the most is horror games. After having played his Tribly games and watched his reviews, I've picked up on the fact we share similar tastes in horror and if he doesn't think a game is scary(i.e. FEAR), I probably won't either.
