Done with several adventure games. We used to do this with my friend years ago, now that it was mentioned I think I'll give him a call and see if we can arrange another through the weekend gaming session.
About the games played:
Monkey Island 1=>4
Space Quest 1=>6
Leisure Suit Larry 1=>3 skip 4 then 5=>7
And tons of others.
As single player, HL2, got the game at 6am and played 16 hours straight. More recent was Heavy Rain, got it at 10am and around 12 hours later watched the ending.
And I'm gonna do all this again on February 4th when Earthrise is released, but that's an MMO so you can't finish it, but I thinl I'll still get a good total 24 hours of playtime on 4th and 5th.
