Bronson H. said: The new Core books and Legacy content live in the same compendium, and can be used in the same game! Your GM can block out books your group doesn’t use in game settings, as usual - but there’s no need to create a brand new game to try out Core content. This also means you can use Legacy content alongside new Core content on the same character, to mix and match old feats with the new if you’d like. A big thank you to the Roll20 team to handling the remaster in this way. This allows me to keep running my Edgewatch campaign with the old ruleset (my players are not yet interested in shifting to Remastered/replacing their rulebooks), along with playing/judging Pathfinder Society using the new rules. I'm breathing a huge sigh of relief!
