I was playing my game had the idea of knights on horse back. This would add a new branch after knight. It would go footman upgrades to knight which upgrades to lancer or or just uses a long sword and shield/spear. the black smith would also have to make a lance and horse armor. The weaver would have to make a saddle. The Shepard would have to collect the horse and the cook would need to make hay which could be made by the farmer.
If anybody has any other ideas please respond.
