So, your opinion is that new players are not staying due to verbal abuse. New players are lasting less than 30 minutes. I do not think that is enough time for them to get abused. My money is on the fact that the UI is complex and even getting in the fight is a bridge too far for a new player.
If I may speak to my experience as a noob to Aces High III as it relates to the subject matter in this thread.
I discovered AH about 6 months ago, started playing regularly about 3 months ago. I'll just bullet point for short read.
1.) Definitely it is NOT the UI that chases away newbies. Fact is, the UI is very user friendly, self explanatory and easy to navigate. (2 thumbs way up Dale👍👍). It takes some rabbit holing just to find Aces High to begin with so I feel any new player to come in will be a fan of flight sims/dogfighting. Pure and simple it is because 1.) Every member of the playing community has 10+yrs on this game, still play AH because they love it passionately and are expert++ skill level. I can testify by experience that even a top ace from another game will and does get thrashed every time he is in the air. It is like getting in the ring with Mike Tyson. Fly 10 min and get shot down instantly when engaging an enemy. EVERY TIME.. Its nobody's fault and another thing, you don't know if the guy you are engaging is a noob or veteran. All you know is it's a yak, or 109, or spit.. Look at what happened (and still happens) to me.
Getting your bellybutton kicked is hard to stomach. When every tactic you try, every plane you fly, vehicle, field gun, whatever you choose will end up being a 1 to 3 hour session of traveling to instant death at the hands of everybody. How long would you play knowing that? Would you Pay $15 to be beaten into submission? With the HO's, Double teams by the perpetual Altitude potatods (hoards), The "hey, follow me to my CV, field, town so my ACK can shoot ya down for me", The guy that Vultches you from the tank thats parked behind the spot where your plane spawns or from above by the Orbiting Spawn Camper.
Thats why noobs run away. It happens to all great games. The community eventually widdles down to about 10% of its peak and that 10% is the truly dedicated diehards.
As for the age demographic in Aces High being mostly over 40. I think it is a flying thing, younger kids haven't the maturity or situational awareness to envision and implement successful tactics.
Lastly, trash talking, belittling, bullying ect. Ect... I will speak brutally honest about this. First I flew with the Rooks for a month, then the Knights for a month, then back to Rooks to join BT's. I never once, not a single occasion did I experience any negativity, bullying by anybody. Not once. I play 3 to 6 hours a day, everyday. Every player i ran into was very very friendly, patient and willing to help when asked. Fact is, I am guilty of sending messages on occasion like "Weak Sauce supersweetheart!! You need to run and hide under mommy's CV skirt so she can shoot me down for you" or "👍👍 Way to go Capt. Kantfight! Good job avoiding the 3 enemy fighters at your alt while you dive past them to Vultch me and Bline to land the kill"..
also, I have not witnessed any of said trash talking you mention in the Melee Arena.
