Im not a fan of subscriptions. They limit player base, they keep younger kids out. You may like that, but it doesn't build up next gen players. Everything just nickle and dime you every single month and you never actually "pay it off". This is a rental approach and it's just endless cash being thrown out month after month. Like for AH, I love the game. But, all those $15 add up to like 2k over time and I still wouldn't be able to play next month if I didn't want to pay.
The best model IMO, is to be able to buy the game for a one time payment of $60. Then you own the game and can play whenever, and the company gets more cash up front for payroll and operations. I don't mind how DCS where you have to purchase a plane, because each module is like a game in itself, and the fact that you can play it whenever for how ever long after you purchase the modules once is what I really like. Having to pay another subscription on top of the 10 I already have is going to prevent me from enjoying more modules down the line. IMO, just trying to convince you to throw money into the wind for ever... AH is the only game I'll sacrifice a monthly sub for. Just because its my favorite pastime, but in all regards I hate subscriptions and I feel its been a major problem why AH never got as big, and then had a declining base over time when more competition came out. The subscription is a block to prevent players from trying the game again after a few month and it limits players. Like, I wouldn't go pay a $15 subscription just to log into chiverly one time to play it and see if i still like it. Its not a winning strategy to me.
