First off, before you start assigning arbitrary values to the software, you should compare Construct to the other engines out there. Based on development, usability, functionality, and everything else that matters, you will find a big difference, especially compared to those that you have to pay for.
You might ask yourself why is it that this free software has developed so quickly in such a short time, and the answer is, it's not free.
Yes my friends, the truth of the matter is nothing of any value is free. In order to get what you want out of it, you must contribute time, and effort, and if you feel that you cant, or don't want to contribute back to the community, then by all means feel free to download the software, and figure it out yourself.
Different kind of free guys, free as in freedom.
