1503 is done technically better, but it is "administratively" limited: tax revenue can not be self-determined, the sequence of actions, construction is more defined by the program as self-determined - their own concept to build an empire thus falls by the wayside. One can act less but must react. Also a view of the entire island instead of cuts in Zoom procedure would have been nice - pity! Besides, it is much better that more processes can be automated and you can concentrate on another.
