Jason VandenBerghe writes, "The ability for players to stop playing whenever they feel like it is inherent in the form! This is not a bad thing; this is a good thing. It is part of the game-design landscape. And if you learn to worry less about insisting that everyone who starts finishes, and put your attention on the advantages this fact of gaming gives you, you will not find a more personally liberating moment in game design than in designing your end.
The question is: How will you use that freedom?"
