First of all kronlc....you remind me of a character from a book I read once "Marsuvees Black". And if you want to know if thats a complement or the opposite you will have to read it(Showdown)
Second (to get back on topic) I like the idea where they atoumaticly do stuff but you can revert them and stuff. So you set this group to gther food they will continue to find and gather food (I mean moving from spot to spot unlike AoE where they finish mining and go "what do we do now?) until you tell them otherwise.
