Sometimes game designers dual/re-license their games. And sometimes they cannot or don't want to update the original rules. Saying it somewhere publicly is usually enough but gets lost easily. This page collects which designers have dual/re-licensed which games and where they have said it.
Not all the games' pages reflect that license yet.

RonHaleEvans wrote "all my existing piecepack games (and the ones I've coauthored with Marty) are now licensed under CC-BY-SA" in a mailinglist post. Further clarified in comments on the wiki (#1, #2) to more precisely mean that they are dual licensing all of their existing piecepack games under the CC BY-SA 4.0 International license.
