I didn't finish to paly yet, and so I didn't finish my report yet, but I finished my civics analyses earlier in the hope that oyu already change it for the next version, because right now the civics are too much unbalanced IMHO!
Here it is:
Civics:
Authoritarian is way too overpowered. You build pyramids and the game is so much easier. Put some unhappiness then, nobody likes a authoriatian governament. Or/and take off the science bonus would be realistic as well, and game balancing.
I would put
Parlamentary civc further in future in the tech tree. Maybe Mass Media. And maybe the hapiness bonus goes out? And off with the -35% of maintence with cities number. 20% of distance is ENOUGH of a bonus. Too overpowered otherwise!
The vanilla religious civics should go back to their original values!
Syncretism is SOO overpowered! As it is a religious war civic, it should have no happiness bonus nor greatpeople bonus! And reduce the -75% warweariness for -10% please! Way too much, specially if combined with other civics!!!!
Antitheism don't work in theory(I didn't tey though). If you got no state religion, then hell, how can you have something that only work in cities with state religion? xD So, if you could change the birth rate to +20% in ALL cities, and take off the unhappiness for state religion and the exp points! Is there a way to put +0.5(ye)

to each religion inside a city? So if a city has 2 religions, then it gets +1 unhappiness, but if it has 3 religions, it still gets +1

because +1.5

is impossible! Look the forests, each gives +0.5

, so in theory it is possible! And make no religion spread please!
Procedural law is strange. Why the religious flavour? Take off everything(also the - birth rate), leave only the build buildings 35% faster, BUT FOR ALL CITIES, not only the ones with state religion!
I like the idea of the
civil rights, but what about take off the

bonuses? ALL of them, specially the religious ones. Simply put this happinesss bonuses: +1

for courthouse(makes sense no? It is civil right after all xD) and +2

for jails! That would be good! Put also +50% birth rate, not 40%, because the +35% of maintenance is bad, but nice!
Trade Unions is too good. Take off the workshop bonus, specially because there is already it in caste system, and it will be OK I believe.
Forced labor is too much of a production bonus. Put only +1hammer for farm and +1hammer for mine, not 2 and 3. And maybe +1

in all cities can fit too.
Socialism is good, but I would take off the cultural bonus. But then, maybe not.
Mixed economy is good, well balanced for specialist economy, because it is good for food, but bad for money(maintenance hehe)! But what is that +5

for the budhist shirine? Only one city in the whole world gets it? xD. Take it off and put +1

for banks! That is not bad.
Citzen army is OK, but what do you mean with "+0gold support cost per military unit"??? It means nothing lol! xD
Pro. army is expensive, but overpowered still. Takes off the +4

bonus in the 5 biggest cities and put +1

for stables

!
Mercenaries is COMPLETELY messed up and makes no sense! You gotta change it all. Hum, what about delete all, then put first +25% military production(if you contract mercenaries you get army faster, not slower), +5 exp per unit, +25% war weariness and +1 support cost per unit! It all makes sense, because mercenaries are expensive, people don't like mercenaries fighting for their own country but mercenaries are normally good and fast.
Militarism: So again ,what do you mean with "+0gold support costs"???
Gov. H.C.: TAKE OFF the penalty for cities without it, because you already have it in other civic in the same category ... Besides the

bonuses, just put +1

per forest in fat cross. Or something like that.
Subizided H.C.: Take off the +1 food per town.
Homeopathy: Take off the no unhealthness from buildings.
Web Classes: Take off the +20% from birth rate.
..................................
So while you don't need to get all the suggestions, I belive that a lot of them are very goood for the balance of the game!
