I vote for all options that are comfortable and easy for the developers and users fairly and equally.
Id say one off payment would always be nice but not with a huge price tag
id say a yearly subscription of small amount would be good enough if not better for scirra and some users personally
id say a monthly subscription will just help their userbase alittle more and satisfy some of the airy heads
id say a DLC model is a unlikely idea but if the price is a lot cheaper 5-10 pound per dlc update every say 1 year and the aesthetic were a lot greater maybe
The best method would be to let people decide how much they want to pay within fair bothways limits and within fair both ways timeframes
and provide decent rewards that don't effect the user experience negatively but effects it positively and then not reward gating them apart
from the initial subscription just giving them free digital stuff
that is always evolving and getting better they should be more like very productive , fun , aesthetically pleasing plugins,etc and
deeper behind the scenes stuff then keep evolving and branching out from their
without burdening others in the process.
That result could possibly lead to a smaller income of say maybe up to a million dollars or pounds whatever your currency is more or less
every month and or every year or whatever but a much more consistent and stable userbase and a lot more passion and activity
then you can just charge a small one off price again every significant number version
Construct 4 , Construct 5 aslong as it's worth the upgrade just for that extra income and I don't think many people would
be pissed off with paying for alittle work right ?
Rewarding your users in evolving intelligent not going to steal your money intentionally ways is always the better way slower but fast in the longrun
it's not badly captalistic because we are paying you for the work in return we are getting a piece of software and free stuff.
I will have to pay the subscription if their is no other option so and paying yearly for me is much better then paying monthly.
