#1 Gameplay. If not for missions, strategic goals, tactical options, ability to simulate WWII fights to some degree, and fog of war, this just becomes another FPS of sorts. Up and fight, up and fight.
#2 Flight modeling, so long as it is kept to pretty much one standard across the planeset, I'm happy. Still see some planes do things *I* don't think they should be capable of sometimes, so some players probably "gaming the game", but that is ANY MMOG..... you accept it and move on, or give yourself an ulcer over it.
#3 Graphics.... I'll take higher graphics, so long as the load if client-side. Be too much a problem if it is server-side, considering Frame Rate issues some folks experience, not to mention unintentional warping and discos. Each player can set graphics to what he wants and can handle on their system.
What is AHII, 600 MB? Most of my games are in the 2 to 5 GB range. Although, the maps in most of the senerios and such look fantastic compared to the war arenas..... the winter maps, the airfields, the large cities.
