I can't play constantly. My brain begins to melt after about 10-13 hours in front of a screen. I completely agree with you though, Tan.
PS: I have watched the first bttf movie at least 40 times: 40 times about 2 hours = 80 hours of "Marty! The flux dispersal will... LOOKOUT!"
PPS: I have almost the entire Back to the Future trilogy script memorized, dead serious.
