I beeline to Mass Media trading with Mansa Musa (a tech monster) and Asoka (holding his own). Washington is an ally but falling behind in the tech race. I fought two meaningless wars with Carthage whenever Asola would ask me to come to his aid. I did capture a Carthagian city (previously barbarian) in the middle of America which I gave to the Americans.
Techs to Mass Media
In 1322, I have finished Mass Media. Unfortunately, I don't have an engineer to build the U.N., any cities with high production, or the votes to be elected Secretary General. Mansa and Washington love me (+18 ratings with common religion) and Asoka is at +9. Hannibal was going to be my opponent in the election. He had captured a few Indian cities in earlier wars but Washington had somehow grown to be larger than Hannibal. When Mansa researched Biology, I knew my plan had some serious problems. Mansa quickly became the largest civ, followed by Washington, Hannibal, Asoka, me, and H.C.
Great People
The new plan:
As I approached Mass Media, I started building an army of grenadiers, rifles and trebuchets. Hannibal is falling behind Washington in population and my plan was to win with Washington, Asoka, and Mansa's votes. All three love me and hate Hannibal and H.C. I plan to attack H.C., take his lands, and immediately lose all the ex-Peruvian cities to Hannibal to boost his population. I can't directly trade with Hannibal without losing Asoka's votes but I can lose a war.
I've never tried giving away cities to win before so its a first try. I declare on H.C. in 1270 and send the start of my S.O.D. to take his colonies on the southern island. I quickly sweep through those cities (H.C. has cavalry but not rifles), promote some of my units, and get my first G.G. (I may have the latest date for first G.G.). H.C. discovers Chemistry and I have to fight some sea battles before landing my stack with reinforcements from Rome near Cuzco. I joined another war with Hannibal at Asoka's request to get to +10 while taking the colonies. After taking Cuzco and Macchu Pichu, I run into Hannibal's stack of rifles and knights. (Don't you have some Indian cities you should be taking?) I trade Nationalism for a temporary peace treaty since my stack is small and tired. 10 turns later, H.C. is reduced to 2 cities and becomes Hannibal's vassal, restarting war with Hannibal.
The wheels fall off the bus
I revolted to Universal Sufferage, Emancipation, and State Property in 1338 and with the help of a golden age I finally complete the U.N. in 1392. I am at war with Hannibal and he should be the largest civ after I lose the ex-Peruvian cities to him. Asoka is already at war with Hannibal and I bribe Washington into declaring as well. Hannibal won't take undefended cities! He keeps attacking my stack of rifles instead. I finally send my stack on a death march to the northern shore to board galleons. Three units boarded a galleon near the southern shore but the rest of my stack is destroyed. Hannibal finally starts taking the Peruvian cites. He razes Macchu Pichu, the second largest city and I sue for peace to give the other cities before he screws up again. He will take Cuzco but none of the island colony cities.
Before I surrendered Cuzco, the first U.N. election was held and Asoka votes for Mansa despite our much better relationship and he becomes Secretary General. After surrendering Cuzco, the first vote is for victory and I get a kick in the stomach. Asoka now decides to vote for me and I am 20 votes short of victory. If I had just held the Peruvian cities the game would be over. Adding insult to injury, Hannibal is rapidly losing votes despite the new cities. I suddenly realize that he is massively whipping his cities to fend off invasions by America and India. Aaah, the new AI is messing with my plans.
Final techs
1370 Steel (trade)
1399 Artillery (trade) Thank you Asoka
1400 Military Tradition (trade)
1415 Steam Power (trade)
1417 Rocketry
The final war
I bribed America and India to stop their wars when I realized the whipping problem. Then I thought, whatever, and redeclare war on Carthage. I land my new stack of doom (3 rifles, 2 artillery, and a grenadier) near Cuzco. India with declare war for free and I bribe America into the war again. I farm the southern island, take a few cities, win the next election for Secretary General and begin the final push. I take most of the ex-Peruvian cities and the Americans capture Kerkuoane. This is enough to push me over the threshold for a 1420 diplomatic victory.
Without the great engineer, I'm too late to win the fastest award if someone else is trying. It was a good game and I learned a lot about the diplomatic end game. I still choose allies too early in diplo games but I'll learn. The stupid, fake war with Carthage cost me about 20 turns but the engineer was a killer.
Mansa Musa is running away with the tech game, his workers are building oil wells and Assembly Line is the only Industrial tech he doesn't have. If I didn't win a diplomatic victory, he was going to launch in the mid-1500's.
