Yeah, I'm using them as an example of an underwhelming product that nevertheless has a market at its price, which millions of people regularly purchase knowing how shit it is because the price is tolerable for a guilty pleasure.

Measuring the time in percentages here doesn't make sense. A 1 hour difference on a 3 hour game can easily be chalked up to variance (even the estimate of 3-4 hours has a 1 hour range) but 10 hours off a 30 hour game is enormous. If we also made it $50 instead of $5 and argued for time per dollar as a value metric, sure, those would be equally misleading, but time per dollar is less important as the total cost decreases. Nobody would say a 2 cent movie ticket is half as worthwhile as a 1 cent ticket. They're both approximately as valuable as the experience itself because the cost is negligible.
