Honestly I don't even care anymore. The poor performance and the headache we have to export our games is annoying enough to leave C2. I think I have dozens of games unfnished because I got discouraged just thinking in the exporting process and it's poor results. Plus all the tools in order to have access to leaderboards, achivements, monetization, etc have poor support in the built-in engine so we have to rely on 3rth parties. Based on all of that I can say that subscription is a NO. Plus most of us are hobbyiest at it and 50% or more of the scirra's audience come from many countries. I take for me as an example. The currency exchange in here is more than 3:1 so I would pay more than 3 times the price.
To sum up I can say that C2 -and probably C3- is really a great tool but terrible at supporting us after the project is finished. The support for mobile and for PC(steam) is terrible if compared to others. We don't know all the news from C3 but we already know that we won't have native export and we can expect the same problems I mentioned above. Based on all of that how can we vote for subscription instead of buying?
