What if ALL digital games gave you the option to do this:

I am perfectly ok with unplayed games sitting in my library. I know that I will eventually play them.

With this method, I would have to buy the game as I advance through the story. I really don't want to be thinking about money as I play through a game. I don't want to constantly evaluate a game to determine if that last section was good enough to buy the next section.

The other issue is what about sales? A lot of the games in my library were bough on sale. Seems impossible, or at least difficult, with this setup.
