I went ahead and founded Washington on the starting position because any other option would have provided at best only a mixed blessing (at least as far as I could tell at the time). Under the circumstances, it made sense to go ahead and build my capital as quickly as possible. My initial scout headed more or less to the north (since that was the path of least resistance in terms of the types of terrain available to move over) but quickly encountered a dead end and turned around.
After giving the matter some thought, I decided to go ahead and build a second scout. That way, I could learn the lay of the land faster and perhaps grab more huts. After building that scout, I then started a granary.
In regard to research, I started off nominally researching Ceremonial Burial but with the science slider set to zero so I was not actually researching at all. The idea behind that move was that if I was researching Ceremonial Burial, I couldn't get it from a hut and would therefore get something more valuable instead if I got a tech from a hut. My hope was that I could acquire Alphabet from another civ (or conceivably from a hut) and then use the gold I built up while not researching to push research into Writing.
Very early in the game, I discovered a site with six-turn settler pump potential practically right next door to the capital. I thought briefly about building a settler before my granary, but quickly realized that Washington's food production is so limited that doing so would save me almost no time in building my second city. Building a granary before my settler was clearly the better move.
In 3600 BC, I got Warrior Code from a hut. I'd really hoped for a settler (which would be especially valuable in a game with no food bonus at the starting position), but at least it wasn't a map.
A century later, I scored a major diplomatic coup. The Romans had just moved two workers into their capital, and they were willing to deal. I ended up trading to Greece and Rome to get the techs they had, thereby tying Greece and gaining an advantage over Rome in technology. More importantly, by obtaining two (both?) of Rome's workers, I both enhanced my own tile-working capacity and crippled Rome's ability to improve its tiles. With how close Rome starts to us in this game, my hope is that that advantage will pay enormous dividends over time. With Alphabet obtained as part of my technological exchanges, I started researching Writing at the fastest pace I could while still maintaining the luxury slider settings I needed (not that I needed the luxury slider right away)..
