I'll see what I can remember off the top of my head, I won't detail too much of the diplomacy, but here's a run-down of my last game (v.4/17) displayed with some screens:
Standard / Continents++ / King / Authority/Fealty/Imperialism/Autocracy
Domination victory turn 371
No impactful game changing mods, with the exception of 3/4 UC
Founded last with Festivals: Orders/Scholarship/Inquisition/Way of Transcendence/Crusader Spirit
My settling phase was straight forward, but I did notice the hit from less barbs due to CS while going Authority. I declared on Inca after he settled in the heart of my land, but his Slingers were formidable alongside mountainous terrain near Antium - he held onto his city and overtook mine, to my surprise. It didn't last long; once I had my Legion and Ballista online I proceeded to wipe Pacha out and claim all the land to my south without worry. The XP bug would ensure I had lots of fighting to come while making this dom victory easier than normal.
With the help of neighboring Hong Kong, Tikal was mine and granted me prime position to finally push into Mayan land... Except the bugger established a defensive pact with not only Brazil and Portugal, but also France (authority), whom I had to be cautious of and had planned to deal with separately; I was sanctioned (essentially the entire game) after the initial WC so unhappiness was an issue and I had no breathing room to fight on two fronts despite having a fur monopoly and passing Casus Belli.
After having to be patient for quite a few turns while sitting on my advanced forces, France does me a favour by denouncing me, followed by a DoW a turn after I denounce him. Troyes would let me control the channel across to his continent, and he had a few islands to my southeast that were of strategic placement. Gandhi simultaneously vassalized Venice (I've decided that although they are performing better since their rework, Venice is basically still a feeder civ that will probably be disabled in my future games, unless I personally use them) and declared on me within the next 10 turns. I capture the three islands and peace out with France while trying to maintain happiness.
I annexed one of France's Islands and built the Red Fort (I was the only Fealty civ, so I had no worry of losing the wonder) to defend my flank for situations like Venice trying to breach my waters. The wonder allowed me to leave the area unguarded for a few extra turns before having an Ironclad come in to clean up the remaining enemies; You can see the CS/RCS with a stationed field gun while I was 2-hitting frigates and 3-hitting corvettes - it felt good to me.
Fast forward 30 turns and Pacal digs his own grave by Declaring on me alongside Brazil. Hong Kong was now his brief ally, but the AI failed to actually prepare it's borders (along with some other weird behaviour like not putting units in the cities to garrison as well as still leaving GG/GA occasionally exposed), letting me walk in and secure my first vassal after an easy war. More importantly, it gave me a great city (Tulum) on the western end of France's continent to attack from.
After 320 turns, France's land is mine, alongside his crucial gem monopoly that would help financially aid my final push across into hostile lands, beginning with an established beach-head against my closest competitor at Pataliputra. I kept Napoleon alive as he was previously voted head of the WC, and it paid off with his proposal to repeal my sanction (at the cost of Peace Accord passing). Choosing Scholarship wasn't ideal initially, but as the game progressed it allowed me to keep up pace with the other AI who started to accelerate their tech with Rationalism down the stretch. Kudos to the AI for getting the citadel placed as I hesitated to place my own.
Although having superior forces, I had to tread carefully around unhappiness (I ended up fighting off a few barb rebellions), so the conquest of India didn't take priority over the fact Brazil's UU (Prachina) was about to come online and he had most of the wonders, including Himeji / Great Wall gearing him towards a CV. The invasion of Pedro went as planned, catching him off-guard as he foolishly battled Portugal briefly, and that's the only opening I'd need. Once I left him on the brink and he had no choice but to join my cause, I began to pinch India from both sides. In a pure stroke of luck, India willingly released Venice from his confines right before I was to attack, enabling me to only have to capture the Venetian Capital from Gandhi's hands while avoiding a fight with Enrico's fleet. It was inevitable from there; Gandhi tried to put up a fight, but couldn't muster much, meanwhile Portugal (who'd been the only civ to not previously engage me) had no answer for my newly upgraded battleships/destroyers. I refrained from using nukes up until that point, but Lisbon was on the receiving end of my first, and that was it for Maria. Game over! I probably could've been more aggressive and won 30+ turns earlier if I really pushed it, this was only King after all, but I took my time and had fun. 50 cities on the dot, most of them puppets, but I did selectively annex a handful of others for various reasons throughout the course of the game.
Some other general notes: Poverty got really bad mid-game, and there was absolutely nothing I could do about it despite having up-to-date infrastructure; I noticed there's not a single building in Industrial that addresses poverty...? I realize I was sanctioned, and the (un)happy actually feels like it's in a good spot lately, but if I hadn't been using the wonderful Casino building mod by
@Asterix Rage that was eventually granting me gold +1 happy across my massive empire, I would've probably lost a city or two to revolt considering it almost happened a couple times anyways. Trader Sid's and Empire State Building really helped me out down the stretch financially and with poverty relief.
I took Inquisition, not only to try the new system out, but because it was actually viable for my situation considering I was last to found. I can't comment on the new purging with pop loss/resistance, but I do know it single-handedly kept me outta the red throughout mid-game due to Maya spamming missionaries. Once I captured Tikal and had to endure a lengthy peace period with Pacal, I was within a stones throw of his Capital and was receiving hundreds of gold every other turn as he kept flipping the city. My faith-game in general was bonkers as the game progressed due to all the instant yields from Orders/policies as I swept across the land.
This is the first game where I had to really utilize Public Works. I've built them sporadically in the past, but this game required many cycles of turns where I built them empire wide in order to keep my empire afloat. They seemed to have functioned properly and provided the necessary benefit.
I've had two straight games building the Global War Games, and I like the new Menin Gate, but it's bonuses are pretty trivial for that stage and I didn't really get any use from it. The silver prize of 25% attack bonus is really what carries that proposal IMO, and I timed my final attacks to coincide with selecting the "Total War" tenet which also provided an attack bonus for 50 turns. I'm pretty sure the 25% bonuses stacked, but couldn't tell for sure due to everything basically just showing up as "miscellaneous" throughout end-game battles in the combat preview.
Pentagon still not giving any XP for the two free jet fighters. Also, I noticed with the recent changes to the military aspects of the tree in late game, that the free jet fighters are received way earlier than they normally would be: that's some true air superiority (although I still think fighters in general are not necessarily up to par with bombers despite having different roles)!
Alhambra's Jinete promo needs to be applied empire wide IMO, considering it's a finisher and is lost on upgrade; It served me nothing really by the time I was able to secure it from France. On this same note, I think Sankore is now slightly underwhelming compared to it's counterparts. A tiny buff would probably do it no harm.
Please for the love of god, drop the GG on Brandenburg and give it a free Military Academy. I know I was playing a domination Rome game, but I legitimately had so many GG's 300 turns in that I was losing track of them all. Also, I still think supply should be shifted slightly; I was approaching like 300 supply by the end while barely being able to keep up production to consume even half of that number, yet tall empires still have to decide whether to even field a navy most games due to lack of supply. I know it's the contrasting nature between the two styles of wide and 40+ cities vs tall and 5 cities, but it just felt crazy seeing the huge discrepancy in size of military that you can achieve.
City strength actually felt okay to me for the most part, but I'll definitely agree that having Vanguard + is OP, depending on if naval melee keep their inherent naval siege bonus, then I can see a case for just consolidating all the city attack stuff into a single promo that's less obtrusive. I purposefully went Bombardment line on all my ranged naval, and it feels like it's in a good spot comparatively.
I find bullying and tribute is inconsequential as the game progresses, and it probably should get a buff.
Guided Missiles were only damaging the garrison and not the city itself. Pretty sure that's not intended?
Despite it being a very obvious choice for Autocracy, I had a really hard time turning down Order. On paper, Order seems almost as justifiable a choice for a lot of different avenues to success. Some of the tenets for Autocracy seem kind of redundant/not entirely applicable, but I realize there's only so much you can create that falls under the main premise of "git gud at killing more". Still, once I got rolling with Autocracy the sheer force at your disposal is definitely tangible; by end-game I was pumping out units at 100+ XP (air units were getting 120!)! I think I just need some more experience using the different aspects of the ideology in varying situations, seeing as I'm accustomed to picking Order/Freedom, before I can really gauge it comparatively.
