This game needs to offer a monthly subscription.
I'm surprised this hasn't already happened. The cost of modules and maps is high to the point where I would rather pay monthly to have access to everything than have to choose just a few things at a time. I'm not sure what a good price would be, probably $10-20 USD depending on what it comes with. There could be separate subscriptions for modules, maps, and perhaps even campaigns. What do you think? I imagine that a side effect of this would be even higher prices for lifetime purchases but hopefully it would still be an option for those who want it.
For those that just got triggered and are in full reddit contrarian rage mode, perhaps this will give you a different perspective on the pricing or the ability to outright buy a module at all. Or perhaps it will just give you more fuel for your hobby of complaining.
EDIT: People are mad as expected. This is where I'm coming from: Pretend you are a brand new player, and you want to fly the F4, F14, and Apache on Nevada, Kola, and cold war Germany. That would cost $430 USD (no sale) . If a subscription for $15 a month gets me everything then I can play this PLUS EVERYTHING for 28 months. After a few months I'll probably get bored and take a break, i pause subscription until I want to come back. In the long run I'll spend a lot less and get a lot more variety making the game more interesting for longer.
