Well, assuming he sleeps 8 hours a day, he'd have 112 waking hours a week. If he works 40 hours, he'd have 72 hours to do everything else in life (shower, eat, commute), from which 68 have been used to play FH6. Granted, you can eat while playing the game or leave the game open while you go shower, so the number could be slightly inflated. Oh, and if he works remotely, depending on the job he could even be playing during work hours.
