Will you be able to role play politically? For example, maybe a central government will have control over:
Which firearms enforcers may use
Vehicle speed regulation
Taxation, anti-monopoly and minimal wage laws for companies
and people who take the politician career path can campaign for their opinions to perhaps change the minds of other politicians when it's time to vote on an subject.
Being able to do these kind of stuff in an RP game would be a dream coming true for me.
I guess that could be made and completely player driven but the implementation of features which helps make this happen would probably be nessesarry
