Hopefully, Doom III will be on Xbox- and I thought it would be interesting to see what everyone's opinion is on the next heavyweight FPS games.

Doom III's technology is completely new- so it by far has the upperhand graphically and atmospherically.

Halo 2 will (most likely) be a refurbished rendition of the Halo engine...not all in itself bad- considering the wait for Halo 2 will be considerably shorter than that of its predecessor.

Gameplay wise, Doom III will be more of a moody- dark, paced horror movie

Halo 2 will obviously be an enlargement on the frantic gameplay of Halo: Combat evolved

My pick is Doom III over Halo 2 by a considerable margin, but I'll be glad to hear any other differing opinions!
