That's the problem for ED with the current payment model i think. Not every user will keep buying new modules, yet we do expect the current sim to evolve and improve with better graphics, AI, MP, dynamic campaigns, dynamic weather, damage model etc etc. A lot of software that requires continues evolution are subscription based and i think that's fair. Offering DCS world for free in the current times with fast hardware and cloud capabilities improvements will leave them behind eventually. I think a monthly subscription of even lets say for example $5 to access DCS world, and then the ability to buy extra modules like we have now would give them the resources to work more on the Core game which is desperately needed if they want the game to survive. We pay monthly subscriptions for our cloud storage, our music, Netflix etc, this should be no different if we at least want this platform to continue. Eventually they will run out of modules that you can develop for this, and it will all come to a stop.
