I personally think HiTech should probably start to work on a new version of the game. AH was great for 1999, very good for 2000, good for 2001, decent for 2002 but the engine is getting long in the tooth and if they aren't careful HTC will Air Warrior themselves out of buisiness.
I would be willing to pay 50 bucks (up front even) for a total revamp of the game. I suspect that a new version is going to become download unfriendly (something akin to FAIII's almost 300 meg download) so a CD wouldn't be too bad an idea.
I guess the question should be: How many of you would be willing to ante up 50 dollars in advance to give HTC the funds needed to create a AH 2.0? I think, along with a money back guarantee that we would get our 50 bucks back if there is no new version in 1 year, would probably be a catalyst to HTC to develop a new game.
