This was really amazing game for me.
Directly after loosing in previous TSG i was able to get my first king level victory, so I think playing these games works good for me.
This i also started with not too much hopes. My target was to stay alive for longer than in previous TSG, so 250+ turns would be great.
Plan was to get 2-3 cities and stay with them only. Grow them vertically, control money income and happiness and try to stay alive.
I settled in start position and build scout, worker, granary, library, war elephant and national college.
My second city was founded at turn 74 east of Delhi at the coast. Turn after i found out that it was a mistake, because only 3 more turns was needed in Delhi to finish NC. Because of that mistake it was delayed and finished at turn 105.
My third and last city was founded north of Delhi at turn 113.
This is how it looks at this point:
At turn 166 there was first war that I know about (Siam vs. Persia). Later also Greece and Mongolia joined and they made peace and declared wars between each other through rest of the game (also joined by Japan later). I was just trying to improve cities and stay out of trouble. I was in dead end in every aspect, but luckily friends with everyone.
At turn 224 Siam (at friendly) declared war against me. I think I'm still felling a bit weird about diplomatics in civ5.
This was the war that lasted through my whole game and ultimately bring my defeat.
At this point i was sure, that it's over. I had practically no soldiers and he's military force at my land was huge. I was disappointed that i won't even get my 250+ turns. But...
He's force crushed on my cities. Not even sure how, but my cities defensive abilities was amazing. Full health infantry attacking Delhi was dying in one attack. At this point i quickly realized, that Canon added to these defense will make them alive and well for much longer and game is not lost yet.
After 250 turns mark i was still there and Siam force was gone. He kept sending some troops but most of the time they didn't even reach my city to attack it. So it was going great
After some time he was trying to make peace, but peace treaty, where i should give all my gold, resources and 2 cities was a no go.
So i kept upgrading while still at war and wasn't even paying attention to it any more. But this was my mistake. At turn 293 I saw, that Delhi was target of air strikes. Make me smile that he tries some different approach, but few turns later i wasn't smiling anymore
It turns out, he has 10 planes in neighbor city to the south and Delhi defense wasn't able to survive that.
It fells a little wrong that there can be multiple aircraft units in attacker's city, but i can defend only with one artillery/anti aircraft unit in mine.
Lost it at turn 298.
I realized my mistake was not having any anti aircraft defense, so quickly start building it in Mumbai, but it was already too late.
It was able to take down one bomber, but with 10+ air force attack it was lost at the same turn. And then... booom:
Siam nuked me!
At this point i couldn't fight with him and he took my 2 cities not much after.
Defeat at turn 314.
Plan was to survive more than 250 turns and I managed to do that. Got a great game and lots of fun with it.
