Not vidya, but here's some free guides for minimal solo tabletop/journaling rpg's. Did't find a rpg thread in the catalouge else I woulda necro'd it. https://www.jameschip.io/games/the_adventurer.html
Uses a deck of standard playing cards. Suits/values determine what happens next in the story.http://dsg.neko-machi.com/hikikomori.pdf
Uses d10's. Less comfy, but has a somewhat satirical element to it. The NEET aspect of it seems relevant to textboard culture.
Do you guys have any less well known rpg's that you've enjoyed over the years?
