From the introduction: Eä Role-playing Game System Standard Rules (Eä RPGS-SR), is the “standard” rules system. This is what most people will (hopefully) be happy to play for many years on end. It attempts to provide just the right balance of detail, speed, and “playability”. It takes more time to create a character and a bit longer to learn the nuances of the rules than the basic system, but allows for a broader and deeper offering of ideas, rules, and options that increase the depth of experience from role-playing. User summary: The Eä RPGS Standard Rules Player Manual is intended to offer great flexibility in character creation and campaign management. The Standard Rules are a significant departure from the Basic Rules, but offer fewer restrictions and more options. N.B. Sections of the Standard Rules manual are incomplete.
