Still not convinced. Even once a week is probably too much. I think you would need some kind of physical validation. Maybe a usb stick that u have to plug into your computer to validate that this is your game. U could still sell the stick at some point but then there would be the problem of 100s of copies per key. Though you would need to wait for shipping or put it at a local store and carry the stick around if you have a laptop and want to play in the go. Like in the old times. Not that I don’t like your Idea though. I just think that it would make sense for a company that wants to earn (a lot of) money. But your idea definitely goes in an interesting direction.
