No: the Kingdoms campaigns are in fact implemented as mods of their own right (CA sells you 4 mods [campaigns] and an upgraded/updated engine), and our tutorial campaigns[*] function much the same way. You would run the tutorial campaigns like you would other mods.
[*] Plural as a general statement of a kind, not as a confirmation that we actually will have multiple campaigns. I have no idea if that ever will be the case.
