Everything he writes in the analysis makes Halo sound better yet he keeps giving Killzone the win without even explaining why
Extras/Replayability/Overall
"Killzone 2 doesn't have any crazy modes outside its single-player and multiplayer options, but the years it's taken for Guerilla Games to polish and perfect this beast of a first-person shooter's two main game types really shows."
So basicaly he's saying I played a ton of the original Killzone so even though Halo 3 might have a ridiculous amount of more options to customize the gameplay and increase replayability i don't really care and i'm going to give the win to Killzone so my favorite game can win. Not to mention he completely ignores theatre and the multiple map packs out for the game.
Labeling something a Halo killer is just going to lead to backlash when it doesn't sell anywhere near as much as any of the Halo games or get as high a metacritic score. Just play the game you enjoy and stop with the silly biased comparisons.
