We''re not going to start charging money just because people think we should .
Yes, and as Ashley said, charging money will also generate more work and responsibilites.
While in theory we could go commercial, we face the same problems as above (overcoming the freely available branch) as well as being obliged to provide customer support, regular updates, put up with pissed off users who want their particular bug fixed, etc etc etc. So right now we haven't got any plans to go commercial ever. Free for now!
And in case you missed it, he also said:
As I said before, we have no plans to sell any version of Construct, and intend to continue giving it away for free.
Side note:
Actually this thread's intention was not about the price of Construct, but what the developers have planned, for now.
These 2 subjects come very close though and I can see that others, like me, are also interested/concerned by that other sub topic (price of construct).
