most people auger b29s on take off(never gets old)
most people auger 262s diving in(painful to watch)
even if they were free.. people would still struggle flying them
reality is.. way perk system is...if you are not completely dense and semi competent.. you can amass more perks than you will ever use..(like these guys with 18k fighter perks)....the game is already that way.. if people wanted to fly those.. but.. they dont
You're describing veteran players, many of whom are adults who have been playing this game for years and likely some others before. An influx of, dare I say, the WoW crowd (be it 'warplanes' or 'warcraft') brings with it a sense of entitlement via daddy's (or mommy's) credit card that rack up micro-purchases so fast your head would spin. Ok, revenue, great. What about liability (whether legal or not - you know, moral)? 'Junior! My credit card statement has several small purchases totaling $180.00 dollars for ... 'Aces high?!' Whereas - 'Junior, my credit card has a charge of 14.99 for 'Aces High?' Dad, may be glad it's just a monthly subscription without nickle and diming the public for more. Hell, he may sub, himself when he finds out folks older than him enjoy the game.In the other scenario, if daddy's smart, he'll cancel the card, be careful not to give the new info to Junior, and cancel the account, immediately.
Not to mention (but I will) that even though Aces High reserves the right to make changes to the game (including business plan) it already has a long established base that enjoys this method so much that many very casual and occasional players maintain accounts for months where they don't even log on but to perhaps check on the account. The only reason mine lapsed, recently, was lack of attention due to busy life issues when I wasn't logging into the game, at all. There's more support than meets the eye on a week day MA roster head count. And that support is for Dale and the way he supports his own player base, I'd say.
So, yes, I believe selling perks would be bad because of the problems it can cause when micro-purchases get out of hand. I believe too many free perks would lead to uber plane chaos, changing the game in an unanticipated way, related to the wish.
(The above is my opinion, preference and predictive take on the situation and does not reflect, in any way, the opinion or plans of the owner and programmers of Aces High.)
