It isn't necessary and it is needlessly complex to have bicamaral legislative bodies. A simple 'house' will do fine.
The main issues should be whether there is a 'written' constitution and if representation is proportionate or winner take all.
Voting blocks should have multiple issues so that not everything is lock step down a single set of issues.
Democracies should be very limited in how they can declare war. This is the major reason the US never never took over the two times it could. In the game sense moving a democratic nation to conquest would require the consent of the legislature, if that's part of the constitution.
A lot of governance issues should be set in the 'constitution', political issues should be set elsewhere. Immigration for example, constitutionally you could have full citizenship, but legislatively you could limit immigration.
The limitations for expansion should be intrinsic to the nature of political structure.
To use the US an example, it's probably the most efficient structure with federal system.
