not everytime you played the game. only if you wanted to sell it cos you'd have to access psn to delete the game and delete your online backup of it(proof of purchase). then it issues you a new code that allowed you to sell the game on.
when you played the game it would play normally, and if you wanted to go online it would auto check if you had a legal online backup (proof of purchase) it cant be no harder than all the security stuff they already doing, you'd also need online access when you first wanted to install the game too. and input the required code.
i could live with that small hassle, just so i could keep my collectibles safe.
