Saga is now in its 2nd edition with all the basic rules in one book and a series of "Age of.." supplements containing boards and faction information. Most of the factions from the original edition are in the Age of Vikings supplement. Crescent & Cross has been replaced with Age of Crusades (original 6 factions + 6 new). Aetius & Arthur was designed to work with 2nd ed so remains in the range. More Ages to come!
