Raire Tabletop Games
How it works: Each game is a self-contained trifold brochure, ready for quick playing narrative-driven adventure. The themes vary pretty widely between games, and the price point means you can grab them all.
Why it's clever: The games work with things you likely already have around the house: some need a deck of cards (for selecting armor), some need pen and paper, some need a D20 dice (for reasons you can imagine).
The whole thing is made by a single designer (hey Theodore!), which is always a little something to celebrate.
Price: $5
