I have realized that a really good open world video game with lots of replay value has an amazing value. $60 at 200 hours of gameplay works out to $0.30/hour, which I am struggling to find anything else I am interested in that has a similar fun-to-cost ratio.
On the flip side, if the game sucks, the average goes way down. Fortunately I'm a sucker for decent open world games so there's a relatively low chance for me.
