Probably insider info. I'm pretty sure hints and cheats were some PR info that were used to publish guids and magazines. Built community and buzz for the games.
Devs would leak this info to magazines/affiliates to be spread in other publications mentioning the game. This was common especially in the 16-64bit era to generate talk.
Your videos have been helping me for over a decade and I love your work. But why have you started playing in 16:9 in recent years? It just stretches everything.
