Creature and Scared Stiff you're paying for looks alone. Game play is very simple and monotonous on both. Neither lasted a month in my collection and I never considered them worth their going rate...and that was when Creature was a $3K game and Scared Stiff was a mid 3 game. What SS is going for now is ridiculous.
BSD is my favorite horror pin with Frankenstein not far behind. Also a fan of EATPM and TFTC, but I've only played them briefly at shows. Wouldn't mind having either in the future.
Phantom of the Opera is gorgeous and has great sound, but takes the cake as the worst playing pin I've ever owned. Bought and sold within 10 days. I'd avoid that one at all costs unless the theme is your favorite of all time.
