Sorry, that's incorrect. You are assuming what you believe justifies a purchase applies to everyone. It doesn't.
I judge quality of experience, always. So I'll happily spend large somes of very good food, wine, clothes, etc. I will spend money to see very short, high quality films, I will buy short, high quality games and for me the purchase is absolutely justified.
So for you it's about not just how much fun but how long, but that's not an absolute as it precludes a shorter experience delivering more fun, which can be very much the case.
Sorry to seem to be arguing. But while people's view of worth can be different, and that is fine, claiming your view is the definitive correct view of worth is completely wrong.
Try to be reasonable... its easier than you think...
