True, you have to take it with a grain of salt. He is definitely the type of GM that comes from an earlier mindset, where it's a bit of GM vs Player mentality. In all fairness though, Gygax was also very like that when D&D started, and the game has mellowed a touch since then. The same goes for Shadowrun.
But yeah, a lot of the info on details and forethought before character action and such is invaluable.
