Rinaldo, we all respect your work and appreciate your efforts. However, I think you would make alot more money if you ask for donations, its straight forward, a lot of persons will just use the standard features and not bother to pay, they will find alternative ways of doing the "WOW" stuffs. Then only maybe a few persons will opt to buy the advance features (since it would appear we can edit the game without it). If you ask for donations however, people will donate because we appreciate your work, and there will be no limit on the amounts you collected. You can try it and see how much you get in a month, then you will see that you couldn't get that much in shareware license. The only way to make money from your shareware, is to take out necessary features (for example, the freeware could view the database but only the licensed version could edit it) in that way people would have to pay because they cant use the tool without it. If as you say only advanced tools will be paid, then my assumption is that the free version will be just as good as CM07, in that case since we were all satisfied with CM 07, we'll all use the freeware version and not bother to pay and you wouldn't earn anything. At the end of the day, just be your respect and reputation, if you ask us for donations, we will give generously (at least most of us would). Think about it.
