The author could save another 0.83$ per package by skipping the included instruction manual.
I think it's safe to assume that very close to 100% of users will have an internet connection available when playing this game, unless they're on a vacation abroad. I would opt for: 1. Full manual + videos on spacedice.com, aimed for use before the first time one plays the game. 2. Abridged version of manual printed on the tube, mainly meant for recalling some specifics of the game.
