I just last week put out Abkronos, which is a World of Dungeons-derived game based on the old Continuum RPG! It's about travelling in time and space to mess up history and rebel against a time-travelling society that refuses to interfere, with weird and horrifying consequences. It's also just 3 slim pages and designed for quick deployment for one-shots (although there are some mechanics in there that can facilitate multi-session play). It's got me jazzed about making more mini-games while I work on my bigger ongoing projects.
