I'm hoping that Sierra revisits the WWII Aces games in the same style as before, but benefiting from advanced new graphics. It would be akin to the upgrade Red Baron recieved when it went to Red Baron II, which I still fly on occasion. I'd like to see an "Aces of WWII" game which would allow you to fly for either Germany, Italy, Japan, England, Russia, America, and even France, though they weren't in the war with their own hardware for long. A few addons would include pre-WWII conflicts such as the Spanish civil war, or the China/Japan war, both of which use less advanced aircraft, or earlier versions of aircraft that would later see service in WWII. Additional addons would include extension campaigns a la the 1947 addon for AOTP, where history is altered so that the US never dropped their nukes and had to invade Japan, allowing more advanced aircraft to see service from all sides. A similar addon for the European theater would be more difficult, since there are fewer obvious events such as this to serve as launching points of an alternate history. I have my own cool ideas for this, but I would be forced to start a whole other post, as it is rather in-depth.
