Man I am fucking pumped, I loved Killzone 2 and I'm sure I'll love this one even more.

Killzone 3 is a must-buy for me. It's the only shooter i'm going to get so far from now until it comes out.

the more I think about it... the more I loved KZ 2's multiplayer... Too bad the single player was bad enough to completely turn me off to the game

I am already planning on buying Black Ops. But I will buy this too. I just don't know how I'll balance playing both online.

I'm still skeptical. Killzone 2 was gorgeous, but there wasn't much else exciting. The multiplayer was better in theory, but the gameplay (mainly the shooting) wasn't up to par with other shooters on the market.

a lot of MW2 additional features were directly influenced by Killzone 2, so i cant imagine how much they're cramming into Killzone 3. i dont think i'll play anything else once its out.
