I also do not agree with subscription at all, this would devide DCS community to people who would commit to subscription and others would end support ED completely (including me). I think this would lead to loss of custumers and other potencial customers like me would be discouraged.
I have about 23 modules + terrains from ED aside from few campaigns and i am very much looking forward to buying even more (Mi-24, Mig-23, F4U, F-4 ...).
So if such thing like subscription model would happen i would buy no more, end for me, NO!
I am also not playing DCS every day, sometimes not even few months. The pricing that is suggested in original post 20 euros would not be justified for me to invest in DCS monthly, i would definitely spend it on something different.
But one time payment example 50 euros for one module that i can play from now on anytime without worriyng about subscription is much better.
Current ED`s model of pricing is the reason why i even started with this sim. Before I was thinking of buying X-Plane but the fact that you basically have to buy the same game every major update X-Plane 9 to X-Plane 10 to 11 and also DLC aircraft may not be supported is to me unacceptable but I see subscription model as even worse, NO! for me.
Please do not even suggest this again.
