Boarding action was definately one of my favorite maps, partially because of the sniping, but also because of the sheer craziness that often happened. You never really knew where everybody was and with the muiti-level design, you could be right below an enemy sniper and never know it. I like the mancannons for teleports idea - kind of like real boarding action. This and sidewinder were the two maps from Halo:CE i wanted them to update and bring to halo 3, and they've already brought us avalanche so, who knows?
