After quite some time of intending to but completely forgetting about it, I finally got over to DriveThruRPG to buy the PDF of Judges Guild's 1978 landmark work, Ready Ref Sheets . This work from the dawn of RPGs, a mere four years after the publication of the original D&D and two years after the white box I learned the game from, has been called the first GM aid. And it is, if not the first, then at least one of the earliest works aimed at GMs but wasn't an adventure or location description (those being heavily overlapping categories at the time). I remembered it fondly from years and years and years ago as a fascinating source of gaming-related riches. On the other hand, I haven't really looked at a D&D volume in the past decade, haven't played in two, and haven't played this particular archaic version since before leaving high school, and for my own gaming needs, there would seem to be very little going for it beyond nostalgia. So how does it hold up?
