Idea for Govt expansion

[Greek_fire19]

Why do we have special area where factions can build certain governments anyway.

I understand that Rome is given a much larger area over which it can build level 1 and 2 complexes, because Rome was good at adapting to local ways and implementing their own way of life in totally different cultures, however surely in 272 BC there was nothing particularly special about Rome in terms of its ability to export it's culture. Say The Carthaginians had won the Punic War and conquored Italy and Gaul; I imagine they would have been as adept at implementing their culture as the Romans.

Obviously I actually have no idea what would have happened if Carthage had won the punic war, but it would not be difficult to argue that a proficiency in assimilating foreign cultures was a consequence and not a condition of conquest, and that it was because the Roman army was so good that the Romans got good at assimilation.

I guess what Im trying to say is, I think that giving factions specific areas where they can and cannot build high levels of government feels a lot like giving the player a 'tram-line' that he has to follow. Obviously some cultures would be easier to assimilate than others because they were spoke similar languages etc, but surely type 2 government involves in most cases large scale extermination or enslavement of the local populace and forceably colonising the area with your citizens. I think the cost and time that requires is well represented in EB and should be possibly in any direction the player chooses to expand into.

Obviously type 2 government means different things for different factions, but you get what I mean.

EDIT: obviously
