This is a great point, but I don't think we're talking about the same thing when we use the word "game". There is a counter-intuitive difference between a sales contest and a weekend spent playing Modern Warfare. One has a real monetary value attached, and the other doesn't. Yet we'd STILL rather engage in the activity that has no real reward attached. To me, that is the sign of a well-designed "game".
