This...is impossible to calculate for me, given the fact that I played half an hour a day for the first three years I had games, then that went up to three hours for the next year, then it became however long I wanted for the next seven years. This isn't including all of the gaming I've done in the car, on plane trips, and those two cruises...and even ignoring the 8-hour flights, that alone is probably months of time, at least. Yesterday alone I played New Vegas for thirteen hours; I'm relatively sure something similar happened five days in a row last week. So...yeah, I don't know, and I'm too busy sorting out the Mojave's problems for the umpteenth time (said as lovingly as possible, I assure you) to really care.
