Longest single session of playing one game?

[Chandler]

My longest gaming session has to be World of Warcraft related. Back in the day when PVP ranks were serious business I had a span of 6 to 8 weeks where my group would pvp for 12 to 14 hours a day every single day just to not drop in rank.

 

I don`t remember my longest single gaming session but it had to be leveling to 60, I had a couple of 30+ hour sessions.
