people seem to think that when your tea mates keep yelling some wacky shit like "yeah, eat this" or "woohoo" it means that games had good AI
Yeah, I've heard some people say that. However, I think the Halo AI (at leat XBox) was decent. Not particularly ground-breaking, but they did a good job with it. Running away and regrouping isn't THAT new, HL1 and Opposing Force had it w/ soldiers, but I've played relatively new games where the enemy just plainly charges at you.
My copy arrived today, and I'm playing it when I get back from work. Hopefully, Internet play is fun, otherwise I'll be pissed.
