I would like to see a version of WaW that has oil and stuff, and that is playable against the AI (yes, the old versions of WaW are playable with the new AI and GUI -I am playing one right now).
It wold ne nice too to have ATG versions (playable against the AI) of WW2 scenarios available in other games like Crete, Korsun Pocket, Kharkov, and so on.
And oh yes, an ATG version of Operation Crusader!
Personally I am not very fond of games where one has to break through three rows of enemy units like some Barbarossa scenarios in other games (I get brainlock with games like TOAWIII). The advantage of AT vs other games is the relatively low count of units and its good implementation of logistics and maneuver. I DO have games like WiTE, WiTP, all versions of HoI3, and so on, but I think good implementations of AT beats them all.
