Gears of War 2 the best game ever? I think that's very unlikely, of the games I owned for the 360 I liked even Kameo better than Gears of War. It's certainly down to personal preferences.
The game had no story, very testosteroned empty-headed acting, too many actions on one button, you feel caged in the linear environment and the game sported some IMO irritating sections like the tank gun part and the underwhelming end boss fight.
I have better expectations for Killzone 2 and Resistance 2 with regard to upcoming shooters.
Gears of War is a good looking game on the 360 (I think still the best looking one currently), but it has been surpasses by PS3 exclusived like Uncharted: Drake's Fortune, Ratchet & Clank: Tools of Destruction and Metal Gear Solid 4: Guns of the Patriots. They also don't suffer from texture pop-ins as badly. Even Epic claims UT3's more open environments on the PS3 looks better and runs better, that's the same less PS3 centric engine.
Gears of War 2 I think will be the best / most impressive looking 360 game, hopefully it addresses the first game's main flaws (sadly there still seems to be the same unrealistic crouched running). I expect Resistance 2 with its massive boss battles and Killzone 2 with its supreme assets polish to go well beyond this. The last video looks cool, but again it seems you're restricted in environment movement, the big guys and sentinals look good, but probably will be midgets compared to Resistance 2's bosses.
Gears of War 2 probably supports good multi-player and IMO it needs it if there's no story and limited game length like the first game. Looks well polished and better than the first one, but best game of alltime I regard highly unlikely.
