So I’ve been getting into rules-light OSR stuff, like Troika!, Into the Odd, In the Light of a Ghost Star, and all the stuff that Highland Paranormal Society puts out. Has anyone run across any products such as this that are geared towards the one GM + one player format? I just picked up Scarlet Heroes, but I still find digging through 130 pages a bit daunting, and those short zine-style games really melt my cheese.
Barring that, what mechanical or procedural modifications would you adopt if you were to run one of these stripped-down OSR games for only one player?
Thanks in advance!
