no the game looks fantatic on the big screen. No jaggies and very smooth. Gears 2 is what suffers on the big screen.
i agree with Gears 2's comment. I played it on the 56" and it looks good, but not super good like a lot of people are saying. To me, Gears 2 have that fluorescent look to it. It's cool to look at it, but it's not warm. I don't know, it's a different visual feeling, when you play the game the first time, you hardly care about such thing. Hell, Resistance 2 looks better IMO.
My KZ2 is still in transit, but come on, saying it looks like GoW2 for the PS2, i find that hard to believe... Don't get me wrong, GoW2 looks good, very good, but nevertheless, it's a last gen game (even it's a top notch, top of its class).
Just saw the HD KZ2 clip on PSN (Christina Lee), come on, it looks great! And from what i read, that clip is generated from the game.
