Went through my Xbox backlog today including X1 GwG and Game Pass games. Did an honest assesment of games I am actually interested in playing and then looked up all the "How Long to Beat" estimates. The total stands at 4156 hours for main game + extras. That does not even include DLC I own or anything PS4 exclusive. That is a number shows just how stupid I am at buying games.
I think it also shows how stupid you are spending time documenting games instead of playing them. I say that as a person that is equally stupid and does the exact same thing.
