Hi! I've recently researched, translated, and put together 70 pages worth of information relating to the Legacy Challenge. This is by no means comprehensive and is up for criticism. My sources are listed on the last page.

Since MTS doesn't allow pdfs, I'm hosting it on my Google Drive: https://drive.google.com/file/d/1Hb...iew?usp=sharing

Inside the rulebook are:

• 
  General definition and vocabulary of the Legacy Challenge
  Recommendation on starting your Legacy save
  Rules for calculating your score if you're playing competitively
  A list of 50+ extra challenges
  Extra lists of all traits, lifetime wishes, careers, foods, collectibles, etc., all sorted by pack.
  A list of recommended rule-compliant mods for a Legacy save

If there's multiple issues/corrections/extra suggestions, I'll make an updated version of this rulebook.

Hope someone finds this useful!
