A lot of the civics I've found to be badly flawed, if not in terms of incorrect reporting of their effects, then in just being... utterly useless.
For example; while Tribalism and Despotism are quite necessary in the early game due to being the only option, or with Despotism having lower unhappiness, their special buildings don't come around until FAR LATER in the game, and the civics have virtually zero benefit once you're past the Medieval Era.
Nobility almost always ends up coming AFTER Patrician, rendering it completely useless.
Senate is GREAT for military production and food from trade routes, but the benefits aren't enough to sustain it if you have severe problems with unhappiness or another option becomes available (like Bureaucracy or President)
Parliament is another "Do not use, ever" options. Pointlessly causes +2 unhappiness in your largest cities, along with +25% War weariness, and the only real benefit is a slight increase in gold... in your capital only. Same reason I never touch vassalage; it only gives benefits to my capital, and by the time these options even become available, my capital is already a monetary/industrial powerhouse 90% of the time, and all my other cities are in desperate need of catching up.
Federal is a definite "Do not ever touch, ever". +100% war weariness, unhappiness for every military unit in a city, heavy unhappiness due from tax rate, a 15% DROP in productivity, and NO special building? Why the hell does ANY civilization pick this civic?
Democracy at least has the benefit of District Offices, but given the up nature of this mod, where 90% of EVERY building that's SUPPOSED to DECREASE maintenance reports an Actual of NEGATIVE gold income, Democracy is pretty much a bane to ANY effective civilization that is attempting to NOT be completely wiped out when the moronic AI decides it wants to go to war with you because... well because you looked at it funny way back when you first met 1,300 years ago.
This is a SEVERE issue in this mod which NEVER occurred for me in the base game; the AI has become like that in "Total War" games---it is only out to declare war on everyone in its path, and it doesn't need a damn good reason to turn on someone it has Free Trade agreements and is on FRIENDLY terms with. Doesn't even matter a damn if you have an army twice the size of theirs, and production capabilities 60 times theirs, and if they are a "Federated Nation of ____" meaning they get +100% WAR WEARINESS, then they freak out and are willing to talk when you take one of their cities, and yet the only terms they'll accept is if YOU GIVE THEM YOUR SECONDARY CAPITAL!
This is beyond ridiculous. Isn't the whole purpose of this supposed to test how civilizations fare with different ideologies/policies, and how best (or worst) they can utilize the policies under certain situations? Like how would Mao's "Great Leap Forward" have operated if they had a huge food surplus and the technology to better keep track of their people and industry?
Instead, we find that some civic choices give huge benefits and bonuses with very little drawback (such as Fascist) and some civic choices that are actually FAVORABLE to the people and absolutely prolific in our day and age (such as Democracy) actually have no major benefits, and HUGE long-term deficits. If War Weariness worked in the real world the way it did in this game, the United States of America would have completely and utterly collapsed due to the wars in Iraq and Afghanistan. Completely and utterly. Every time I play a game as a Democratic nation, get out of fighting a war, and get right into fighting a JUSTIFIED WAR OF DEFENSE, a significant portion of my cities go STRAIGHT to HUGE war weariness where people are STARVING and the food levels drop by 20% each turn.
What this mod has taught me is that the best civilizations in the world have these civics:
Fascist
President
Nationalist/Marxist/Liberal
Regulated
Volunteer Army
Free Church/Secular
Superhuman/Socialized/Corporate
This is beyond ridiculous. The ONLY balanced civics in this mod are Economy and Welfare, and to a very small degree, Religion.
