I'd love to buy AH and keep it going. A pipe dream of mine. I'd just need to hire a coader. Wouldn't change much. I'd fix match play, remove some maps and continue to add new ones, and adjust radar back to where it was, but just make it harder to take down radar, and perhaps adjust some other things like the clipboard without tabs on the online selection screen, and ask for help from the community. Id probably add other payment options like $50 packages or other marketing incentives, something like that. Promote special events much harder. That being said, this game doesn't have to die. Infact one commercial on a mainstream channel would be a huge boost id recon, even in the short term. Very little people in the grandscheme have heard of this game. Hitech could possibly eventually put this game into a free to play list with those hundreds of other classic games, or something like that so it stays available for ever. I don't know how that works but it could be a possibility.
Still a very fun game to play and still better than WT and IL2 IMO for its own reasons.
