Truth be told, I didn't expect the release of Age of Crusades so soon, and not before Book of Battles. If something is lacking in the new Saga iteration are scenarios. Probably A&A ones can be used for v2, and that is what I intent to do -hopefully, in Easter, when I can take a short holiday!-. I had thought about designing my own, but I don't feel that I know the quirks of the game good enough to design scenarios. Not just yet, at least.
Anyway, I am looking forward to AoC release. Particularly, because of Mongols!
