I was reading this thread http://www.gamesas.com/topic/1442065-how-many-hours-do-you-reckon-you-have-put-into-morrowind-since-its-release/ and got me wondering what your longest sessions have been?

Well I would say that the longest I ever played Morrowind would be about 18 hours straight. Probably did it a few times.

For other games I've played Torchlight 2 recently for 20 hours straight. I also played Civ V for 18 hours. I don't play games that long normally, but when I get a chance to play games with a group of friends it's usually rare so we play for as long as we can.

Back when I was younger, I easily logged in some 6-8 hours session. (or longer)

But now I usually just do 1-2 hours.
I spend more time in the CS making mods, though.
