I've been coming up with various ideas for the basic outline of this system and am having a bit of trouble with handling combat...
ie. Goblins raid your town, and your guards try to fight them off. After chasing the them away, you decide to hire a band of mercenaries to take care of your goblin problem.
How would the guard combat and mercenary combat get resolved? Actually conducting every individual combat sequence would be far too slow, imo.
