Played a game of Civ V. The gods of RNG gave me Haile Selassie on an island map. I led Ethiopia to a glorious cultural victory (with the Order ideology, natch). (King difficulty, past that it feels too unfair to be fun.)
The AI really can't into navies. My first (and only genuinely important) war was when America backstabbed me (as it WOULD), and I obliterated his forces by buying a couple of galleasses with my emergency backstabbing war fund, and bombarding them to pulp. Then rolled into New York and annexed it for a nice early-game advantage.
A bit later I joined Ashurbanipal to my south in another war against him and snagged Washington DC. We left what was left of his empire between our glorious nations as a stunted buffer state, and continued as ironclad allies all the way to the end. Nice guy, Ashurbanipal. I guess I had misjudged him from previous games.
After that I was in the #2 spot, with Pacal of the Maya holding #1. Then Pacal got into a ruinous war with his neighbour Shaka, which sorted out that problem. Catherine of Russia tried to backstab me but I got intel on it first, and when she sent an invasion fleet, I sank it. She was most upset from me from there on out, going to the point of adopting the Autocracy ideology -- but my superior Order prevailed and a violent revolution forced her to join the Communist bloc, even if she remained something of a Tito to my Stalin. Before then, she did make one more stab at taking me down, by allying with Pedro of Brazil and Swylawablwewswoup of Siam and launching a concerted attack, but they too fell before my invincible navy, and I ended up with two more capitals in my empire.
At that point I was already well on the exponential curve; only thing that could have stopped me at that time would have been everybody else uniting against me. In a game against human opponents that would very likely have happened, but not with the AI. So from there on out it was just cruisin'. I took down Pacal and then grabbed Shaka's capital to pass the time, but other than that it was easy-peasy.
Really, Ashurbanipal was an excellent comrade.
