I have not gotten to check out the 'Zilla game yet (been super busy with the first few weeks of my store being open) but I've read the same thing about the manual, and downloaded the revised instructions.
RE: Betrayal at House on the Hill - I've seen you guys playing that one a few times in pics on FB. We have it as well, but it says it's for 3+ players. Do you guys have a third player? Or are you playing a custom 2 player game?
