I am concerned about the base time needed to finish a game, not how long I could hypothetically spend playing it. For example How Long To Beat clocks Skyrim at 32 hours, I think I put in about 60 before I had enough and made a beeline for the ending. Similar thing happened with Breath of the Wild and the same is happening with Final Fantasy XV. Finishing a game is important to me and if all ~60 hours suddenly become mandatory then I'm out.
