The differences in the timeline make the performance of the political system noticeably distinct.
Due to the relative independence of the states, the state legislatures nominally hold greater authority... but some things fundamentally don't change. As long as circumstances permit, the Eastern Country still adheres to the centralization gameplay.
Concentrating power to achieve major objectives is an advantage, but sometimes when policies descend to lower levels, they come with not only twisted and deformed versions, but also various unsuitabilities to local conditions.
In this particular timeline, due to the relative self-reliance caused by extraordinary calamities in various districts, the parliament's responsibility for coordination has become significantly heavier.
