Online Registration. Kind of like how Bioware does it with Mass Effect 2. You would get a one time code in with your new game. and if you buy the game used then you would have to pay a small fee (Like 5 or 10 dollars) and of course make the game High Quality. Needs to be an experience!
But if I were to ever become a game developer. I would probably try to be a Western Japanese RPG creator. and I wouldn't tack on multiplayer just for the sake of having it.
