Its easy to be critical of this game. However when you compare this game to the other flight sim MMO's such as WB or FA, AH is significantly better. Graphically online gaming will probably never be near offline game standards. Bear in mind the mega corp game companies don't like to produce niche games they want the mega sellers. There are very few flying games coming out offline, let alone online. And none that I know of by the mega corps. Currently, my favorite game is Over Flanders fields and its a WW1 mod for CFS3. Graphically it beats AH. But sooner or later the lack of real opponents will get old.
I think AH is a good product, not perfect but a good product. After playing AW from its beginning until the end though I would have thought that online air combat would be farther along than it is. Online gaming provides a key component that offline games don't; real people, unpredictable results. I'll take gameplay over graphics any day. AH is the best flight sim online. WB and FA... Been there rejected them both.
As far as AH using up so much resources I am surprised how little it actually requires to play the game. You can build a bottom end AH game computer for $500 or less if you can use a lot of old parts. Hardly a resource hog. Give AH another 10 years and see where they are.
