Notes:
- Timeline covers all boardgame variations included in the Compendium
- Unknown dates are inserted approximately where they belong based on the best of my knowledge or inference. In some case it was possible to estimate a year of release, and in other cases it could be determined that one variation was released before or after another, even if the dates themselves were not known. If even approximate timing is not known, the date is labeled as “Unknown”. When approximate timing could be determined, the date is labeled as “Unknown (est.)”.
- For anyone who needs it, a key to the flags appears at the bottom of this page.
