Things I have thought about in the past 12 hours.
*Kite golems. Most likely as Asian, ninjaesque spies.
*A series of short PDFs called “The Twist!” each one gives a single game-mechanical bolt-on option for a creature, encounter, location, or items, and discusses ways to use that to change existing things to focus on new stuff. Like, a simple template that turns any creature into a ghost possessing its own dead corpse. A deadly trap that has killed so many psychics, it has become self-aware (and both hates its existence, and feels it must fulfill it’s core function). An archetype that lets a cleric be the only worshiper of her god, in all the universe. A complex family tree, with both great heroes and ancient tyrants, that can be used to slot any PC or NPC into a vast and storied geneaology.
*Modern spells with joke (but thematically appropriate) components. Like something that makes poison safe to eat, but requires ketchup or pepper; or one that lets you fire a fiorearm without reloading, but requires a DVD of an action film as a focus.
*A fantasy stronghold that is headquarters and working churgical center of the Order of the Knights Hospitaller, as a site for adventures, or a base of operation, or a way for GMs to allow PCs to fix any character-ruining ailment, but only after completing an adventure there.
*A time traveler who can only go from one bordello to another, because it’s the World’s Oldest Profession.
*A new category of Spell Dragons, broken down by school (Evocation Dragons, Divination Dragons, et al)
*For a near-future setting: Remote drone flying taxis called AirLyft.
*According to this note I scribbled down while sleeping – “Th band is the hive.” I’ll see if I remember anything more about that.
*Also “Twinkie porn.” … I HOPE I was thinking of a Pinterest-like site for people who love to look at pictures of interesting twinkie recipes.
*Genre Mash-Ups. Old West Vikings (“Longarm”). Post-Apocalypse Jungle Book. Tron/Transformers (Cyber-Tron).
Some other stuff I have written down in the other room…
