I know the Crusades have been discussed and it is something I would like to see but I thought the early Reconquista would also be interesting. Seeing that a lot of the fighting seemed to revolve around raids these rules would seem to be ideal.
Not just the early Reconquista! I don't know of anybody who does the Almohads, but it would be great to be able to fight around the campaign of, say, Las Navas de Tolosa.
Volo vincere cum meis, vel occumbere cum eisdem.
I second this idea. Las Navas de Tolosa alone would fill two to three kickstarters. 😉
