From the #RPGaDAY2017 challenge (info here):
Which RPG does the most with the least words?
I am super-frigging tired today, and my wrists and hands feel like I'm probably on the verge of developing carpal tunnel syndrome, so this will be a very short post.
[my yard project DID get done, though, so...yay]
Fortunately, this is a pretty easy one: the Holmes edition of Basic Dungeons & Dragons gives you plenty of adventure material in its 40 or so pages...probably the most efficient word use of any RPG ever published in print. Enough to get anyone started and run plenty of sessions.
Close runners-up include Twilight 2000 (there's a LOT of white space in those slim books). and classic Traveller (you can get huge mileage from the original black volumes). But Holmes does the most with the least; his game gets the nod for this question.
