Upon reading this I could just imagine the poor adventures cold, miserable, ill-equipped and covered in mud, sheltering from the heavy rain, there moans about the Baron 'volunteering them' suddenly interrupted by the roar of The Beast in the distance. This strong evocation of setting isn’t even the best bit of this One Page RPG, the best bit is the way The Beast is incorporated into the world.
Both of the Weakness tables and the Wants, and Lair tables all embed The Beast deeply into its setting, and influence the world of the game. Other touches are nice such as the equipment rating, and the 18th Century setting (yes, flintlocks!), but the stand out thing is the Beast generation tables, Lots of meat to love on this beast of a bone. (5 out of 5 Stars from me).
