not one person here would have a problem paying...not one!... if the game had been released in a state of near perfection with very few bugs most IL2'ers would have there credit cards set to auto draft for the next release.
the IL2 community does not have a problem paying....remember we spend hundreds if not thousands on our rigs just to play this game
...but the quality must match the cash.
My 2 pence on the OP original question is this...i think pay per monthly is not a good motivator for the developer...DLC could be but that would be only if the core game was as i mentioned...close to perfection. This is a niche market...but so is Bugatti...they have people willing to pay because they deliver
happy new year to all
