whats the longest time in hours youv spent in a dungeon? or in game days in a dungeon?

0 I actually never got around to playing arena or daggerfall

I spent about 3hours and too many game days in Scourg Barrow, I had no idea how to get out of there...
I don't go dungeon crawling much...

probably close to 2 hours before I said, "screw this, that noble can find her own damn gem."

Then I got caught trying to break into some house. That was the icing on the cake and now Daggerfall hates me.

I think it was a couple hours. I was being very thorough and making a point of stealing anything of value I could find in the whole thing. I was also a fairly low level and had trouble with some of the baddies in there.
