Atm i think 30$ aint to much, for two reasons:
1.AH support is really good, if u compare it to other sims, bug fixes and new version are published every 3-4 weeks.
2. Atm AH seems to have a real good Flight Model.
But soon(er or later) WW2 online will come out, prices so far are teh pirce for the retail and 10$ per month, with a realistic FM, with the option to play much more than only pilot and vehicle driver.
And i guess than the AH price will for many players no longer be good. The ultra realistic hardcore sim pilots, will try out WW2on, on will probably stay there, cause u will have to work for a kill there.
Also with its command structure and european map, original countries etc. WW2on will give WW2 fanatics much more opportunites to play.
Sooner or later AH price will drop, or HTC will have to give the community much more for the 30$.
