I have similiar issues with games. I dread open ended ones - Witcher, Skyrim - because of the prospect of them never ending. But it's worse than that because the least resistance in gameplay and I will abandon the game. For instance, I've haven't been able to play more than 10 minutes of Cities: Skylines because it gets overwhelming.
At least now I accept that I don't have to finish games. That it's ok to even uninstall one after a couple of hours of play if they don't bring me any more joy.
Also, there needs to be a category of game guides for those of us who prefer small quality gaming experiences over fillers.
