Yeah, I feel ya. I cannot gauge myself the same way as I only play one single player game at any given time. I like to at least complete the main story and side content to my satisfaction before starting another game. Multiplayer is a bit different, but there is less story involved in those games.
So when God of War came out, it was all I played until I got the plat. When Breath of the Wild came out, I played 130 hours before even touching another single player game. My general rule is if I start it, I finish it. So my total hours of available playtime is what dictates my choice.
I do very similar for games which lock me in, Resident Evil Rev 2 was one that had me hooked but I do love the "last time on resident evil" which brings you up to date if you stop playing for a day or so and it keeps you informed of the previous plot points which are going to come up in the coming area.
Breath of the Wild got me hooked for 320 hours, even as a €60 game (bought the dlc not to play it but just to give them another 20 for a masterpiece game) but yeah that's still coming in at around 20c per hour of game.
Darksiders warmaster edition was for sale on the ps4 last month, it cost around a fiver if I recall, bought that of course as it's really great game, great value... played it for exactly 0 hours, so the same calculation brings up an error on a calculator for value, as you cannot divide the cost by zero hours of playtime.
