Parenthood was in fact a driving force behind this game's form factor! As for short adventures, some of my personal favorites have included…
- The Haunting of Ypsilon 14 (for Orbital Decay/Cosmic Highway, originally for Mothership)
- Dead Planet, especially the one-page-dungeon "The Screaming on the Alexis" (also for Orbital Decay/Cosmic Highway, also originally Mothership)
- Ultraviolet Grasslands (for Exiles; see also Luka's "Deep in the Purple Worm," from One Page Dungeon Contest 2012)
- Aeon Wave (for Inner System Blues/Resistors, originally for Fate Core)
