I had no intention of participating in this GOTM, because I know I am not ready for Deity. So I decided to try something just to see what would happen.
I never built a city! I just had my worker, settler, and scout exploring!

I sent my settler east and the scout south and then west. Traded communications and maps to get me just 2 techs (currency and construction) short of entering the middle ages! With a little more careful planning I might have been able to squeeze 1 more tech out of the deals. I ended up buying Literature for 40 gold and never did get the government techs. Even if you have only 2 gold, some AI will demand that from you, so I spent most of the game at 0 gold.
My settler freely explored most of the Russian, German, Persian, and Egyptian territories. They ask you to leave, but you usually can spend hundreds of years in there territory before being forced to leave (just don't keep popping in and out of their territory). Since they eliminated the exploit of where you could plant forests in AI territory (to starve them), I was irrigating Russia's mines and mining their irrigation!
After awhile I got bored with moving my units around (and my map wasn't worth selling anymore), so I just fortified them wherever they where. Eventually my settler that was down by Egypt got forced to move out and ended up on the other side of the world by Rome. My barbaric Iroquios people were dumbfounded to see Roman bombers and English battleships.
Without a city, you get no notification of wars so I had to guess who was at war by watching the cities exchange hands. Of course you get no notification of when someone declares war on you, until you've lost your scout or worker.
1730 A.D. Egypt killed my worker. Got peace several turns later for free (because I had nothing to give!). 1796 A.D. Persia kills my scout. Got peace for free with them too. But they signed a trade embargo with Japan against me (how can I even trade????). Shorty after signing peace with Persia, Japan lands 2 infantry and 2 cavalry right next to my settler, so I knew it was over (my settler was trapped on a peninsula, so it couldn't try running). Rome was polite to me during the Egyptian war, so Rome and Egypt must have been at war.
I out-survived Russia and Germany, who were both taken out by Persia in 1250 and 1380 A.D., respectively. Persia was on the way to domination when I lost, they were in the process of conquering Egypt. Funny thing is, the AI entered the modern era around 1300 A.D., yet no one had finished the spaceship when I got killed at 1814 A.D. I finished, with of course, 0 points. Persia had 4500+.
