These games are so long that they become more than just games — they're stories, campaigns. It was a pleasure. The new mod, the new leader, the well-thought-out map, and the jeeeez these wars! I never stopped learning and can be proud of many attacks I directed.
China grew and became strong enough that its rivals had to gang up against it. It claimed the top 3 religious wonders, mastered teleportation, and reached production heights through corporations I've never seen before.
It fought back the world leader across 3 wars, over several months, with unyielding tenacity. But in the end, it wasn't a stack of doom or higher tech that led to China's downfall — it was the borders. Carthage secured all attacking chances with its position fortified by a better canal system, better prepared border control, and Kremlin-boosted production. The nukes on China's navy sped up the inevitable, but Carthage's superior air force, positional control, and endless bombing runs set up positive trades for a steady conquest. Meanwhile, North America and the Netherlands closed their borders after witnessing China attack through their territory, effectively trapping China.
Even the strongest walls can become cages. It was only a matter of time.
T316 Update:
T294: Gira won UN Election (all 4 voted for Gira). Charts now show the huge power dip. I started West Point for my own +26xp units in Small World. Xist razed Mediolanum.
T295: Gira finished 3 Gorges Dam.
T296: Coldrain has an ICBM.
T297: Xist captured Battleball. I recaptured, but can't raze my own cities
T298: Xist launched 4 Tac Nukes. Major invasions: South sea is flooding with Battleships creeping in, west border filled with Tanks, north sea filled with navy.
2 nukes on Neapolis, 2 on Ravenna (both with Bomb Shelters).
I had enough army nearby to fight back the land invasion.
T299: xist launched 2 ICBMs around Bloodier Clock. It wiped most Carriers, 8 - 10 Destroyers, 1 (empty) Attack Sub, many ground units. I voted "No" to the "No Nukes" UN Vote. Y'all put me through it, I want you guys to deal with nukes, too!
T300: UN vote passed. I get 0 ICBMs even though I whipped to finish one last turn! Xist captured Wingspan. I lost the 10 - 20 ships I had in the south due to turn timer, not a huge issue, though. 12 Hill-moving Marines
marching on Ravenna. Coldrain finished Apollo program project.
T302: Xist razed Boss Monster. Xist tried to take Dominion, but a single Knight survived! I founded BosserMonsterer where Boss Monster was. Hopefully it will be more boss and more monster than before.
China Map:
T303: Coldrain offers open borders, I accept. Xist hits BosserMonsterer, 1 SAM survives. Xist's navies set up blockades in the north and south seas. Islands are starving and pissed.
T304: Xist captured Battleball and razed Carcassone. Coldrain and Gira are still putting EP into me

I'm a dead horse, even xist stopped ages ago.
T305: Xist captured Betrayal HotH (last northern island city) and launched another land invasion on our western border. I have 0 Workers left. Damn. I learned that nuclear fallout can go away naturally - never knew! Xist finally completed Ironworks.
T306: Gira issued U.N. Diplomatic Victory vote. I abstained. You gotta do some triangle diplomacy or something for that victory. If you cancel borders with me when I'm already fighting an uphill battle, then you can't count on my vote even if I dislike the other guy more. Xist nuked my 2 loaded Tactical Nukes and it killed them - I'll never get to nuke this game

I also didn't realize 1 nuke could kill 2 nukes like that, or maybe I miscounted. Xist razed Gloomhaven (capital) and Neapolis.
T307: Lots of starvation + unhappiness. I cleared xist's Hill Marine force and founded a new, non-coastal city near Gloomhaven's ruins: Hnefatafl (a.k.a. "Viking Chess" or "Tafl"). Fun assymetric game where white's king is trying to escape and black tries to surround it.
T308: Xist captured GoT, my central southern island. He's been hitting coastal cities and brought 8 Tanks through NA.
T309: Xist captured BosserMonsterer and Dominion, my last northern coastal cities. Re recaptured them. He nearly took Bloodier Clock, too. Coldrain is leaving the 8 Tanks in NA rather than closing borders. He didn't want me hitting Xist but has no desire to slow down Xist's conquest. I set up my Commando Tanks (upgrades hidden) to hit Carthage, I may be able to raze 2 cities.
T310: Xist captured Age o Mythology, BosserMonsterer, Patchwork, Dominion, my entire north coast. I recaptured them. I know he's getting better trades, but this should slow down his conversion on them. (He leaves 1 - 4 units in each)
T311: Gira issues UN Vote to stop the war. I want to say "No", but that's disruptive when Gira + Coldrain need to be working against Xist and want as much on their side as they can get, so I vote "Yes". But my math shows this vote still might not work... Xist razed Hnefetafl and captured BosserMonsterer, Dominion, Twilyt Struggle, Age o Mythology. I recaptured each of them.
T312: No vote result yet? Coldrain completes SS Docking Bay. Xist captured many more cities. 4? More? I can't recapture, railroads disconnected. Xist cleared my Commando Tank force. I was 1 railroad short of getting to have fun

I rebuilt a few Workers and some mismicro (didn't notice some inner railroads bombed) left me 1 Worker action short of blitzing through and razing 2 cities.
T313: UN Vote failed. Xist didn't even need to defy, his population is too high! Xist razed another city. Gira and Xist closed borders. Xist offered peace for Small World. No.
T314: Xist captured Small World, Dominion, Hues and Cues. Coldrain DoW'd me. I'm down to 8 cities, collapsing fast. I still kill whatever units I'm able to, especially when a Commando Tank is in range.
T315: Xist rushed the 3 cities NA was targeting. NA left them alone rather than DoW xist for them. I recaptured 2 of them. With the 25 - 30 units I have left, I set up my last stand in my favorite city - can you guess which one?
T316: Xist took another 3 cities, NA took 3 cities, I'm down to just my favorite city.
