Well, I guess now I'm no longer the really horribly old one around here any more. Congratulations, maybe?
I'm amused that your grandson found the game scary, but what do kids know? They've got no context for judging things. I found Young Frankenstein
scary the first time I saw it, and I was about seven or eight at the time (1974). And I had a cousin who was absolutely terrified by Clue
(the movie). I'd be interested in knowing what he thought were the scariest parts.
I wonder how'd he'd like it as a bedtime story
