Also, it looks like there is a demo for HALO PC now - 130 odd megs. I was so amped to get it when it came out, but i didnt, and I noticed there really hasn't been too many people playing it online (stats at gamespy.com) - SO, i skipped it. I'll get the demo and sheck it out tho.
Update: Eh - its pretty weak. A lot of fun on the xbox with everyone around, but on the pc is seems SO sluggish and just really boring.
