As much as someone might want to daydream about AH becoming a FPS or subsim .... it's not gonna be. We have the best WWII fighter plane sim complete with some tanks/vehicles and ship task forces. Other than that, we have auto drunks to capture fields (or not). If you were to write down every element of Aces High, the planes, vehicles, ships, shore batteries, terrain elements, cloud environments, etc. then it might become evident how full and rich this game is with an amazingly small and talented staff to support it.
(Besides - this is a 'wish list' item.)
