Even though it's an ES game, I think the devs might sneak in pop culture references from time to time. Here's one I think I may have found: The Wharf Rat - a tavern in southern Haven. Wharf Rat is a song by the Grateful Dead about a down and out alcoholic. Considering that a lot of older devs and programmers were Deadheads back in the day, this could certainly be a reference to the song.
Has anyone found any others?
