Sword & Backpack on dice

TLDR: Dice are cool. 

... each player should possess a personal 20-sided die. The die is used to resolve combat, make skill rolls, and so on. Sharing a die is fine, but it’s weak magic. In Sword & Backpack, dice aren’t just tools, they’re a direct line to fate, a link to the great mystery. As such, they should be respected. Your personal die should be carried in one’s pocket at all times. It’s a totem. Respect it as such.

You can find a primer on, and links to, Sword & Backpack here. S&B is a tongue-in-cheek presentation of the simplest RPG rules imaginable. Basically roll a d20 and see how high or low the result is. Sounds simplistic, sure, but what more do you really need? Also, the formatting of the rules is kind of cool; the small pages are meant to be printed, cut out, and pasted into a pocket-sized notebook.
