If you go to the HTC homepage, then Help, then Getting Started, then Game Play, the first sentence reads:
"Capturing territory through the use of air, land and sea power is the objective of Aces High."
Then you read this first introductory paragraph on the home page, the main page of the site, and all it seems to talk about is fighting, battling the "science of vintage WW2 air combat" and "High fidelity air combat." Not even a mention of field capture, nor one elsewhere on the home page as far as I could tell (with the exception of some generic "the battle rages 24 hours a day" which could mean the war or it could mean intense fighting.
Aces High takes the art and science of vintage WWII air combat and sets it in an online high intensity environment where hundreds of players can battle it out with and against each other. High fidelity air combat is the heart of Aces High, but it doesn't end there. In addition to flying a multitude of aircraft types, players can also man vehicles, boats, amphibs, gun batteries, and ships. It's the most diverse virtual arsenal available to players in this genre and it's constantly growing through frequent updates. In the air, on land, and at sea, the battle rages 24 hours a day with participants from around the world.
Unfortunately, intense player vs. player combat is contradictory to what is currently the most efficient way to win the war (for much of a map). That doesn't have to be the case, but for now that's how it works out. This is a game infrastructure issue that is up to HTC to solve, or not solve, as they see fit.
