I've used other rule books and guides to Dune, but didn't find them sufficient with the way my mind works. I instead wanted to know what was happening in each round and what particular factions had exceptions to that. This 1-page guide is the result. I find that using this makes a great quick reference to make sure nothing is forgotten while you're playing as well as a handy guide for teaching the game to new players. This guide isn't thorough enough to act as a replacement to the rules. It does include the optional rules as well as some common house rules.
v1.1 includes a few minor omissions that others wanted to see in the guide.
v1.2 some minor organizational changes.
