There is no technical limitation that would disqualify an IL2 "class" engine from being used in a massively multiplayer game. I've seen screenies with hundreds of planes in IL2 (AI of course), so the engine does handle large numbers of aircraft. They just lack the net code. As Superfly pointed out, expecting such results from such a small development team is highly unrealistic. Right now, graphics wise, the only thing I don't like is the old explosions, smoke, and that there is no additive filter on the flames/muzzle flashes (against a bright background the flames appear darker). However I'm sure these features (and more) are coming, right now HTC is working on the basics to get the game online. I am not at all disappointed with AH2 ... frankly all my experiences with it have been positive.
