Back in the 70s I did the same with the available sources. Nobody but me gave even a vestige of a shit.
The efforts of the Game Master are often overlooked, always thank your GM after every game! Especially when he is a great GM like Nick J .And that is the perennial GM vs Player problem. The GM produces something that is really good, well-researched and could be used throughout the game and the Players say "cool" and move on.
