Reminds me of the fatalities in Mortal Kombat growing up. All the regular moves were in the manual, but IIRC the fatalities were not. It was a form of secret knowledge, and it was really cool if you knew one. Granted, this was right before the Internet-connected home computer became ubiquitous.

GameFAQs very quickly democratized game knowledge the way Wikipedia did for general knowledge a handful of years later. I learned the infinite 1up stair trick in Mario[0] from a sibling before that, but had the most fun with stuff I could look up.
