With the arrival of Edition 3 the biggest changes are the tables, summaries, diagrams, and index. They have made the distinction between tables in the rules and summaries clearer. The summaries are now at the end of each major topic, as well as a overall summary at the end of each step. There are nearly three times as many diagrams, and each diagram is larger and clearer than before. The index is now five pages long, making it much easier to find rules.
