[3] 1615AD - Luis offers Copper in exchange for Iron. Strategic resource for strategic resource, now that's what I call a fair trade.
Sure, Luis, we'll accept. For now. I mark "Find Copper" on my TODO list. Saladin wants to trade world maps. Nah. We already have all the info about the world we need, and he only has a piddly 40 gold, not worth the trouble.
Philly completes its drydock, and starts on - you guessed it - a settler.
Corinth builds the courthouse, and starts on a Forge, because it has a few hammers available, and hopefully one day it will actually be able to build things without rushing.
Portland is founded at Yellow Dot East, and starts on a Theatre.
I queue up a workboat, due in 1 turn, before the settler in Athens, because I realize the clams north of Athens don't have a fishing boat on them.
I rush the Library in Thermopylae to speed up the development process, cutting 13 turns down to 1.
[4] 1620AD - Boston completes a Grenadier, starts on another one, since the defenses on the main isle are a little bit thin. Sparta completes a Bank, starts on a Grocer, since health might soon become a problem there. Thermopylae completes Library, starts on a Bank, since there is a bunch of commerce there.
I rush the Theatre in Portland (25 turns to 1), and Courthouse in SF (9 -> 1). I also crank the research up to 100% again, so we get RP in one turn.
[5] 1625AD - We get replaceable parts, start work on rifling.
SF builds courthouse, starts on Bank, because why not.
Portland completes the Theatre, starts on a Granary to promote growth.
I don't rush anything this turn, as I am out of money due to deficit research at 100%.
[7] 1635AD - NY completes its drydock, starts on Cavalry, because I reckon we might want to attack someone soon.
Athens completes its settler, and starts on a workboat for Portland. Speaking of Portland, I rush the Granary there.
[8] 1640AD - Settler is built in Philly, loaded onto the waiting Galleon, together with an escort and sent Westward. Philly starts building a grenadier. Athens builds a workboat, and starts on another one, since Portland has two naval resources. Speaking of Portland, it starts on a Lighthouse. As I move some things around, Civ4 crashes, and I have to reload at 1630AD. :/
[9] 1645AD - We get Rifling, start on Steam Power. Washington builds the national epic, starts on a courthouse. Athens builds another work boat, starts on a Frigate to accompany our invasion Galleons. I also rush the banks in Thermopylae and San Francisco. And then the game crashes again.
This is very odd indeed, because it's never crashed on me this much before. In fact, in all the time I've played before I think it only crashed twice...
[10] 1650AD - Boston builds its Grenadier, starts on a rifleman. SF builds bank, starts on an observatory. Thermopylae builds a Bank, starts on an observatory. St. Patrick, a great prophet is born in Washington. Luis and Mansa are at war. St. Luis is founded on Light-Blue Dot East. Also a bit of rushing is going on, too.
Three people is fine for an SG, just means the turns will get back to you faster. If you would like to avoid that, and if more players don't show up, you could increase the turn count to say 15, or 20, for now. Untill things get messy. 
Same thing with Mansa. No need to give him ivory. He can have something that cannot be used to build units, instead. 
If somebody wants to take it, I don't blame ya.
