I have played games for a few hours at a time before on my PS2. When I play World of Warcraft, how long I play varies, depending on what I'm doing. Sometimes just a hour or so, and other times it is much longer.
Seriously though, I play often two hours per day, usually late in the evening after being done with watching a movie and reading on the 'net. During weekend, if I am at home with nothing else to do, these session can extend to 6 hours a piece.
Oh and Hal, there's nothing wrong with you. I have to ask though, have you ever tried playing games? Or do you just not see the appeal?
Later I owned the original "pong" game for TV, and graduated to an Intellivision game console which played things like "Asteroids", "PacMan" and "PGA Golf".
My nephews are so into their "games" (they've got X-Box, PS-3, Wii and several Gameboys) that their interpersonal skills are seriously lacking! They even use them (or their IPods) during meals instead of participating in conversation. It is quite troublesome to me.
Don't forget it was a long time ago and our arcade were mostly filled with pinball machines (The 6 Millions Dollars Man one was fun)
