Good afternoon!
I have an idea but do not know how to start developing it, so I would ask for help and advice here.
I'm thinking of making a licensing system for my games, ie you can download the game and when you start to ask you to put a license, if you have it, allows you to have the whole game, but if you have not closed the application.
This is an idea, the other would add a whole application purchase within the App, the problem is I've seen many hacks to pirate these services and I do not wish this will happen to my games, so I thought of a system keys.
The breakdown would like to do once you entered the password, do not ask again unless you reinstall the application.
Well that's the general idea, I wonder if someone could aid me with this idea.
