From this thread:
I see your point, though an area with seemingly endless maze-like hallways might just get frustrating or annoying for players, particularly if they aren’t keeping a visual map (the fun of that kind of maze exploration was always drawing it out and fixing the mistakes when you realize it’s wrong, though that was also often a cause of arguments which TB quite cleverly tries to avoid in most cases, so that’s probably why you keep mapping in game). I might go with a Pathfinder test if they were lost in some abandoned warren of the underdark just to avoid an hour or more of meaningless frustrating play. But then, maybe TB isn’t meant to be played in an abandoned warren of the underdark? It does seem like TB is about discrete locations packed full of “fun” rather than sprawling labyrinths. But the Pathfinder skill isn’t a bad compromise if you feel like a sprawling labyrinth is appropriate to the setting and idioms in play at the moment… at least to me.
