Anyone who has bought MineCraft will be aware of the system.
You register with the website, buy the game through PayPal using the same name as you registered with, the website system automatically gets updated with usernames that have bought the game, and those users are allowed to download updates when you log in using the username through the software.
I'm not sure how anything made with Construct could utilise this approach (though I'm sure it's possible), but in general, how would someone approach this setup?
I'm just looking for an overview of what's required really.
Although I won't need to put this in place just yet, it's something that I think would be useful to know.
Any help appreciated.
