A re-post of a reply in a different thread but more appropriate here
The game is basically the same game it has always been:
-Giant multi-player 3-way battle of air sea and land vehicles.
-objectives and action is determined only by the desires of the players in the arena.
But people come and go due to a variety of reasons...
1) health reasons
2) financial reasons
3) life priority reasons
The reason they are not quickly back filled with new players is a matter of conjecture. Coming from a house of gamers I feel the biggest factors are:
1) it takes a good gaming rig to play. by contrast a PS4 or XBOX is $400.
2) the competition for MMOs is much larger than it was when AH started and is growing everyday.
3) The game really required peripheries [stick, pedals, throttle, TrackIr or Oculus] to enjoy fully. this adds extra hundreds of dollars to the investment to play.
4) The game is very difficult. To not get slaughtered on must learn the game, plane controls, flight, the view system, gunnery, and ACM. This takes hundreds of hours and will only be attempted by die hard fans of the genre who come in with desire to master WWII air combat.
5) Fans of the genre are a shrinking demographic. Fighter pilot news reports ended 40 years ago. kids want to be a virtual LeBron James now, not a virtual Chuck Yeager. When was the last time you heard a "squeaker" in the arena? It's pretty rare. No it isn't because of 200 channel rants. it's because they have different idols now and the computer world allows everyone to put on the their virtual persona. This new generation doesn't know what a fighter pilot is.
So if you want the arena full you have to make the following changes (in my opinion):
1) Make a version for XBOX users that allows then to use an XBOX controller.
2) Allow cross platform play in the arena so XBOX players can play with PC players.
3) add an off-line story to play through that acts a training class so new players can learn the game, controls, and the skill set to play in the arena.
