Say a simple (hours enjoyed playing)/(price of game) equation. How many hours (you enjoyed) per $ do you think is reasonable/expected? Or is there other criteria for you?

I feel like I'm on the upper end here. But to be fair I also tend to play things that has a lot of replayability. So I usually reach 100+ hours on my favorites eventually.

Eager to hear how others reason about it.

Edit: Added the enjoyed part. I agree with the comments that frustrating hours shouldn't be included in the measure :)
