Public Relation Public Relations Public Relations. If you advertise, they will come. Bite the bullet and place those advertisements on multiple platforms. Cable TV, Netflix, Youtube, Popular WWII websites, etc.
Give out 1 month subscriptions in magazines! I dunno.
I realize it's not my business nor my money, but I would like to think that the reward of an influx in customers would be worth the risk.
Love the idea of putting an ad on late night cable; Adult Swim/Cartoon Network type of channels would be your demographic. hardcore youth gamers who've started to grow up... but not too much!
Gamers who are starting to get disposable income, those that are owning their first credit card, those gamers that played flight simulators as they were in their infancy and simply don't realize there is this amazing game and community.
It was by pure dumb luck that I found this game... I was looking for a flight simulator (actually trying to find the old Secret Weapons Of The Luftwaffe!) when I happen-chance stumbled onto Aces High. Point is, if a gamer doesn't know about your game, game over.
P.S.
HTC and co. ignore me and finish up the amazing looking AH3 please... Then we can worry about growing the player base off of that polished gem...
