I am mildly surprised that I missed HYPERBOREA 3E when it hit Kickstarter. It is extremely retro, all the way back to pre-AD&D D&D, and deep into Lovecraft, Howard, Clark Ashton Smith, etc, etc, etc. Thirteen bucks seemed like a reasonable price, especially since all the artwork is likewise going to be a nostalgia-driven return to your childhood, when all the gamebooks had staples and colored illustrations were a pointless luxury in the interior pages. Check it out.
