I just finished watching two let's plays and a longplay of the DOS game, The Quivering. The reason it was 3 separate plays was that the first guy gave up upset after 2 hours and the 2nd two guys gave up 30 min before the end upset and because what the thought was a bug,longplay was just to finish it

Longplay was just to see the last 30 min. I think there was no bug, just a very confusing way to pick dialog options that they didn't figure out. I usually just watch LPs of games that are obtuse and I judged this one perfectly. Confusing puzzles and frequent deaths were common
