The traitor in Betrayal at House can also get into super easy win situations too. One game the traitor wasn't revealed explicitly and had the key to the objective and just wouldn't give it up, everyone knew after a round or two and she just ran from people/monsters and there was no way for us to kill her or force her to trade with us due to the positioning of monster spawns and amount of empty space we already cleared. 2-3 rounds of this realization we just called it and said bad game.
Other play throughs have been much more interesting than that one for sure, its just the amount of time invested for crap shoot is a big turn off.
