Murdy has also come out very strongly against upcharge mazes with his limited venue space. He said it would be a betrayal to the fans. Don't count on it.
I mean...of all the Trapped reviews I've read none of them were really happy with the value. Even of people who liked KSF overall. The only positive reviews I heard were from people who got to do it for free. The skeleton key rooms didn't seem popular either.
And with such gold star scenes like that, I can see why. It makes sense at KSF which has a cheap event with a ton of large venues hanging around. HHNH which is an expensive event with very limited venue space makes much less sense.
