I feel like Persean League and Sindrian Diktat are way too similar.
In terms of construction they feel like it but they don’t in terms of lore.
The Hegemony is a conservative “democracy”. Concerned mainly about policing the world. It’s a military dictatorship without a dictator. Which means it in effect acts more like a one party meritocracy or
politocracy*. Kinda like what you could imagine the US would be come if we are unable to get over our worship of service members.
Tri-Tach is your standard science mega Corp that got too big to be considered a “company” and of course is entirely immoral.
The Diktat is a fascist dictatorship pretty explicitly.
The independents are... well pirates but they don’t call themselves pirates and want to hide behind an idea of neutrality for the time they’re not breaking the law. They are potentially the odd ones out because the Persean League is similarly constructed.
The PL is the odd one out here because functionally they’re independents who banded together against the hegemony. (So they’re NATO or the EU, but more NATO). So they should look like the independents. Part of the reason they’re the odd one out is that their fleet doctrine is at odds with their core identity. The other is that they’re way too big. A non-unified polity shouldn’t have a unified fleet doctrine or barely even a united banner (but we might need one for ease of political representation in the game)
Most mods exacerbate this fact because rather than putting their independent faction that dislikes the hegemony in as a part of the persean league or independents they add them to the game as their own faction.
Now ideally it would be possible to have factions that locked their relationship status permanently or semi-permanently. That way you could have the persean league be 10 different factions (each with their own unique doctrine) and when modders added factions that are, by fluff, essentially persean league, they could remove a generic PL planet and replace it with their unique faction.
Then you could have the Heg, PL, and TT all be hostile to each other but friendly to the Diktat, who is hostile to the independents, who are friendly to everyone but the diktat. The Church is freindly to everyone. The pathers hostile to everyone but the Church and independents. And pirates hostile to everyone.
*to distinguish the fact that people who succeed in the military are not necessarily meritous as people might assume the word means but rather adept at politics.
