I really don't know why this myth persists so much. We had thousands and thousands of players downloading AH... and almost nobody stayed. The subscription rate was abysmal. THAT is the core problem - for whatever reasons, people don't like it enough to stay and hand over $15. Everything else results from it. That's why HTC stopped advertising... you could not recuperate the costs. Of course, this is a more unpleasant truth for us fanboys, our beloved game ("nothing wrong with it") being rejected. I mean, I was totally surprised how the steam launch ended up myself. 
The gaming industry changed. Subscriptions went away for the new games coming out. All you had to do was buy the new version and you were good to go. Many you had to have/run your own servers. With that change in mind set players have a hard time doing a game subscriptions it seems.
Then there is the game itself. 2 weeks is nowhere long enough to see what the game has. The many ways to play it while all still in the same arena. The learning curve to become average is up there and that is may be only one facet of the game (fighter, GV, bombers, strat, base takes, base defense, sea battles, sea/shore battles......) Luckily setup was made easy by HTC unlike some of these other games. Sure tweaking your setup may take months, but you can be flying in a very short time.
I think the steam effort failed big time as I dont think HTC expected the turn out they got. Had they had the VR all set, a bunch of volunteers ready to help as players came in, maybe even changed a few of the default settings to help new player come in they would have captured a lot more subscriptions. As it was we had hundreds of players check in, get lost trying to get rolling and leave in the first 15-20 minutes. I think finding out the "FREE" was only the first two weeks didnt help much ether.
By some of us pushing YouTube channels and now the Discord and trying to post info about the game every where we can is a small effort to be those "advertisers". I have had a number of people reply to me that they didnt know about or didnt realize that Aces High was around. We all have to get the word out. Join the Discord, post in it, tell others Discord servers about us. The same goes for the YouTube videos. Make them and post them. If you cant make them push them, share them, post them to other social media "X" "reddit" or any other thing you can thing of. The more we can push the name Aces High out there the more likely we will get more to come in here.
