Whats the longest time you spent playing a game?

i spent about 14 hours playing a gamepvtvaladez

when Tony Hawk 3 first came out for PS2, I brought it home around noon and played it until midnight, so 12 hours, my thumbs were so sore, i couldnt use them properly for days

Playing a game with few interruptions...um, I think about 12 hours. MGS2, I spent all New Year's Eve playing it...I almost missed watching the ball drop because I lost track of time :P
