I can't really pinpoint an exact number, but on average, about 2 hours on weekdays playing games. On the weekends it's often over 6 hours per night gaming and perhaps another 2 watching Netflix or Amazon Prime movies. It really depends on a very simple math formula.
How many beers I've had, divided by how many hours it took me to drink said beer, plus the number of times I've screamed obscenities at the TV for dying 8 times in a row, equals whether to watch a movie or continue playing!
