The GameSpot comparisons are so superficial. Really, if you want unbiased and professional video comparisons, there is no better resource than the [url=http://digitalfoundry.org/blog/]Digital Foundry[/url].
I'm usually not a big fan of shooters on consoles, but Killzone and Halo are two exceptions. Not only because, for once, the gameplay via the pad is better than via the mouse, but most importantly because those two shooters have been specifically *tailored* for their host systems. Halo 1 & 2 on the Box are just plain gorgeous and play beautifully. Not surprinsingly, I was very disappointed with the PC port, and Halo 2 on Vista doesn't look like a breakthrough either. Sure the jeep tires are more detailed, but who cares? The Box version used shaders 1.3, yet it's still a joy to look at. Halo 2 on Vista? No thanks.
