Whenever you open/close doors, certain sounds are played depending on the type of door. Big metal doors have the sounds you would expect, as do wooden doors.
Anyway, on certain doors I very audibly hear a sound identical to a door opening in Daggerfall. I couldn't describe it, and i have nothing to record it with. but I'm sure there are Let's Play's/vids that have the sound in them at some point.
Anyway, I was just wondering if it's legal for a game released in 2007 to have sounds copied from Daggerfall, with no altering as far as i can tell. If not I'd like to report it to Bethesda
