I've got a copy of Mastering Pac-Man! It's fun reading, and quite different from Kubey's book, that's for sure.
Pac-Man, as far as I can tell, was the progenitor of game strategy guides. There were books written about playing and/or beating video games prior to Pac-Man (Tom Hirschfeld's 1981 book How to Master the Video Games, for instance) , but that little yellow orb with the pie-shaped wedge opened the can of worms. After that, you started seeing guides written specifically to explain strategies for Defender, Donkey Kong, Centipede, and so forth. From there was born the idea of books written about individual games. :)
This right here was my first Pac-Man guide though. Also from 1982, published by Pocket Books. 32 pages of full color illustrations for $2.25. Eat your hearts out, Uston and Kubey. ;)
Everybody wrote one of these things at some point. :D
Mastering Pac-Man in 2014, "by popular demand". What goes around comes around. :)And if you're interested in a better copy, @cryplectibles, Uston re-released
