Why not all the Hype? What else is there to be hyped about? Boom blox sequel? The way I see it is I loved Cod4 but need a new fix, a new online shooter. I also loved rainbow 6 vegas for it's cover and tactics and I like sci-fi futureistic films like Terminator and Blade Runner.
So Killzone is right up my alley, a futureistic, realistic, gritty, tactical first person shooter. And great physics and graphics to boot! With a nice cinematic finish : )
