Quarters

If I could set the price to twenty-five cents, I would.

Quarters started out as a short, short tabletop role-playing system thrown together for the 200 Word RPG Challenge a few years ago.

 Now its back and doubled in size!

These rules are extremely minimalist but entirely functional, provided you have two coins to rub together. Besides that, it's all you need to have make-believe adventures with some friends.

Official character sheets can be had from any purveyor of fine office supplies.
