Probably because for some of us it is a sickness. I was just having a conversation about this game with a friend at work. Started crunching some numbers for an average. So with The Show 16 figuring on average of 1.5 hours a game for franchise so far this year I have logged over 970 hours finishing 4 years of my Nationals franshise. That is not including Spring Training and the multitude of Minor League games I have played. Nor does this include my RTTS careers, of which I have 3 and one of those is in his 6th year.
So I guess if your play a game that much it kind of sticks in your head, you know.
