The longest I've had was around 10 hours straight....That was a good night.

Been a while since I last played but at least a solid 2-5 hour session.

3-4 hour sessions

I think my longest session was around 13 hours. Now I play for around 2-5 hours.

I can still spend ten to twelve hours straight on one character, but I have to avoid repetition of some Quests or I get bored.

3-7 hours

The longest session I've ever pulled was close to 16 hours when I first got Skyrim for PS3.

Now I play about 4-5 hour sessions on PC.

Today I got on Skyrim at 9am. It is now 23:25 and I'm still playing Skyrim. I'll be on it for another 3-5 hours.

I play Skyrim atleast 12 hours a day but I sometimes take breaks from Skyrim.

Edit: The longest I have played it was almost 48 hours.

Edit 2: SKYRIM!!!

Nice.

Between 2 and 4 hours.

When I'm addicted, 8+ hours. In a typical session, 2-4 hours.

Don't get ES online or your life will be over!

Every day since 11/11/11, from about 12:30 pm to about 5pm, then fix dinner, then from 6pm to 9pm. Except on Tuesday nights because of NCIS and NCIS LA.

Around 3 to 6 hours sometimes. Gotta eat so food always makes me stop playing xD.

About 3 hours...

I lack the fortitude to continue without breaks.

Cote de Pablo

In my Morrowind days I used to play 6+ hours at a time (excluding snack/bathroom breaks) every day. But as I've gotten older I find I have less time and energy to devote to games. I have less patience for puzzles and micro-managing stats. Nowadays I play for about an hour at a time. Then I take a break. I do other things around the house and then I come back. I play for another hour or two and then take another break. And so it goes...
