I just got an Xbox, so I am in the early stages of building up my library. With Halo 2 nearly upon us, I was wondering if I should still bother getting Halo 1. Are there any features from Halo 1 that they took out in Halo 2? Does Halo 2 still support 4-way split screen on Xbox? Does they throw all the levels from Halo 1 into the sequel as a "classic campaign" or anything like that? Basically I'm just wondering if you think Halo 2 makes the 1st obsolete.
