Can't comment on whether I like it or not since I have only installed them. Till I have the time to sit down and get into it it is just easier to jump into AH when I get a small window to actually play a game. Just figured I would mention it.
This probably goes both ways. I guess there is people who are actively playing WT or IL2, and have downloaded and installed AH, but cannot find the time to configure and/or try.
The difference to your case is, that if they find the time (or free up their time for that, having "no time" but playing is just making up excuses) to try AH they are looking $15/month compared to $0 currently. In your case, you already paid, and it doesn't matter for them if you try it or not. But even with a potential reduction of monthly cost you choose to not free up sufficient time to even try.
There's quite some inertia. Seems like peoples comfort zones is with exactly the configuration and flight-models they are used to. Any change would mean an immediate reduction of skill level, with new learning required. Probably one of the reasons why there's still as many players as there are.
Understanding why there's still players left might help to understand how have we lost so many people to this wonderful game (hey, that's right there in the subject) and then maybe why there are no new ones.
- no motivation to re-learn flying (see above): prevents new players from other sims
- want to complete the collect-25k-perks achievement: not interesting for someone who never played here (I guess no-one ever said "ok, let's start playing word of warcraft to complete all achievements", that works by becoming addicted first and then choosing the most time-consuming goal available)
- married to the community: prevents new players (married to their current communities)
- scenarios / special events: not really motivating much for new players, because not much can be experienced during the two free weeks; also, aren't their kind of game rounds in the other games, which are basically little scenarios, minus human interaction and flying around for an hour to maybe end up in a fight?)
- prefer the open-world war aspect of the main arena: the only thing where AH is really different?
Anything missing?
