Oh, your missing it Easymo-
It has all new terrain textures much better than Nuttz's even (well almost), roads for tanks, tunnels and a train (it just goes back and forth in one sector) a huge score board by the windsock near map room/hanger to track wins. The RENO Air Race course is really sweet, if not a bit goofy.
All kinds a neat stuff, but it's still just a dogfight arena. Probably to get trash like Animal out of the Training Arena.
Can't the HTH guys get in?
