frostcircus: I liked his Painkiller review because it allows me to legitimately say "I liked Painkiller before Yahtzee made it cool." I feel like a big man.
It's one of my top 10 (possibly top 5) games of all time; you should've heard me gushing when it first came out: "Seriously, it's the most videogame videogame ever! You'll love it. It's so unashamedly trashy, like a distillation of everything that's ever been awesome about action games so far. It's almost like a parody! You know those ridiculous fake games they show on TV when they want to show that a character's playing a violent videogame? It's like one of those. It's the exact game the media thinks we've been playing all along. It's brilliant" and so on and so forth
In conclusion, Yahtzee is great (Angry Videogame Nerd, not so much, and it baffles me how often he's mentioned in the same breath)

Weclock: is it a character or does he really care so much about a video game?

DrStoopid: Both of these games have something in common. Namely, they were initailly written by small dev teams with the aim of making a fun game. Not sponsored by big publishers only looking to make money. I say "initially" because at some point, Valve took on Portal but I think by that point, it was too late for it to be ruined.

fuNGoo: Also raising the undead threads is not cool. You'll unleash an outbreak of undead everywhere.

Wishbone: It's part of his evil master plan. He's an urban zombie, see? Maybe that's why he still thinks 1337 is cool :-/
Sorry zombie ;-)
