After modding the killing rates, movement speed and some prices/size on units and testing it (a real hard work for us who had the game 3 days ago) I think it would be the next level of modding.

I am wondering if we can add a new cirectory let's say Imperial campaign II and Imperia campaign 3 and put there another date for starting/ending and a different composition of the settlements/owners.

Testing now, next monday I'll tell you if that works.
