" Aside from a few minor quibbles, the Codex Celtarum is simply an amazing book. It’s not just one of the bestCastles & Crusades sourcebooks ever, but it’s something that ANY fantasy game setting can pick up and use/adapt, especially if they are looking for a Celtic flair for their homebrew world and stories. There is so little in the way of mechanics, that you won’t ever have to do that much converting, especially if you already use an OSR system. As usual, the new Celtic content line for Castles & Crusades continues to impress. "
