What I really look forward to are the diversity of the weapon designs. At least thats what I think--judging from the screens it looks like each tribe has its own version of a particular weapon, especially our favorite little disc-spitting weapon of mayhem. I'm judging this purely on observation since its all I really have to go on, I'd appreciate it if someone would correct me if I'm wrong. Aside from that I'm really looking forward to the single player campaign.
