Hi, this was an interesting topic, so I thought I'd have a go myself. In order to make a comparison, I also played my game until 1000BC. I forgot to take a screenshot though

, but I'll edit this post later when I've got one. Until then, you can have a report on how I did, and here's a copy of the game:
Civ 3 Save
At 1000 BC I have 8 cities, 10 technologies, reasonable defences, and a good number of archers. I also have a settler ready to build a new city within a few turns.
--- Report ---
4000 BC I moved the worker one square southwest and didnt find any special resources. I founded Istanbul on the starting location. Istanbul is building a warrior, and Im researching Pottery at 100%.
3950 BC My worker is building a mine.
3750 BC My worker completes the mine, so I start building a road. My warrior has been completed. I leave Istanbul building another warrior and send the warrior north to explore.
3650 BC My worker finishes the road, so I move it two squares northeast to the opposite side of the city.
3600 BC My worker begins building another mine. My warrior has reached the north shore and is now heading west. Ill build another city on this square later.
3550 BC My second warrior is completed. This one moves south to begin exploring. Istanbul will build a third warrior.
3500 BC My culture has expanded my borders. Istanbul also increased to size 2. I increase my Luxuries rating to 20% and lower Science to 80%. I put the second citizen to work on the square where my worker is constructing a mine. The first warrior will continue to follow the coast around to the west. My second warrior reaches the south shore, and will follow it to the west from now on.
3400 BC Istanbul completes the third unit of warriors, which will remain on defence. I allow it to construct a fourth unit of warriors. The worker completes my second mine and begins another road. Istanbul will now grow in 8 turns. It will take 2 turns to build a warrior and 6 to build a settler. I return my Science rate to 100% so that Pottery will be completed next turn.
3350 BC I researched Pottery and decided to go after Ceremonial Burial next.
3300 BC Istanbul completes the fourth warrior unit, which will head east to explore. Construction of a settler will begin. The worker finished the road and moved one square north. I reduce Science to 90% so that I can afford the unit.
3250 BC The worker begins a road. The new warrior finds some cows.
3150 BC The worker completes the road and moves northwest.
3100 BC The worker begins building another road. My new warrior finished exploring to the east, and finds the area uninhabited. A change of plan: Ill build my new city one square southeast of the cows. The warrior heads there to defend it.
3000 BC The worker finishes the road, and moves south, southwest and southeast. Istanbul completes the settler and begins construction of a granary. The settlers move northeast and east towards the new city site. Science is reduced to 60%.
2950 BC The worker begins clearing the forest.
2900 BC The two warriors begin moving inland from the coast to explore the middle of the continent.
2850 BC Edrine is founded and begins construction of settlers.
2800 BC The workers clear the forest and move northeast to begin a new road to Edrine.
2750 BC We discover Ceremonial Burial and begin researching Iron Working. Science is once again increased to 100%.
2630 BC The first two warriors meet in the middle. One turns west to continue exploring and the other heads east to my next city site.
2550 BC The worker finishes the road to Edrine and moves northeast to the cow.
2510 BC The worker begins a mine.
2430 BC Edrine completes the Spearman and begins work on a settler.
2390 BC Istanbul completes the Granary, and begins a new settler. The settler and growth will coincide at 6 turns. Science is reduced to 90% to pay for the Granary.
2350 BC The worker completes the mine and begins a road.
2270 BC The worker completes the road and moves one square southwest to begin a new mine.
2150 BC Istanbul completes a settler and begins work on a spearman. The settler moves northeast, north and northwest.
2110 BC The worker completes the mine and moves back towards Istanbul.
2070 BC Edrine builds a settler and begins work on an archer. Science is lowered to 80% to pay for the units. The settler and warrior escort are sent towards Istanbul. The warrior moves southwest and west. Bursa is founded and begins construction of a spearman.
2030 BC The workers begin constructing a road. The settler and escort move to occupy the same square.
1990 BC The settlers move west.
1950 BC The settlers move west again. We discover Iron Working and begin on The Wheel. Our exploring warriors are ordered to head to the iron deposits to keep watch for signs of enemy colonization.
1910 BC The settlers move west again. Istanbul builds a spearman and begins on settlers.
1870 BC The workers complete the road and move west. The settlers move southwest.
1830 BC Iznik is founded and begins to construct spearmen. Edrine builds archers and begins on settlers. The worker begins a new road.
1700 BC Istanbul completes settlers and begins work on archers. The settlers are sent along the road towards the workers. The workers complete the road and move west. Bursa builds spearmen and begins work on archers. The warrior at Bursa, heads northwest to finish exploring the dark area.
1675 BC The settlers head southwest. The worker begins a road.
1650 BC The settlers head south.
1625 BC The settlers head south again. The workers complete the road and head west. Edrine completes settlers and begins work on more spearmen. The settlers from Edrine are sent towards Istanbul with the existing spearmen as an escort. We also discover The Wheel and begin work on Alphabet.
1600 BC The worker begins the last part of the road to Iznik. The Istanbul settlers head southwest. The Edrine settlers move southwest twice and then south.
1575 BC Both bands of settlers take a step southwest. Istanbul completes archers and begins work on more spearmen.
1550 BC The Istanul settlers found Uskudar and begin some spearmen. The Edrine settlers move south. The worker completes the road and begins a mine. The warrior exploring to the north will remain on the mountain on barbarian watch.
1525 BC Bursa completes archers and begins building some more. The Edrine settlers found Izmit and begin working on archers.
1500 BC Our borders expand at Istanbul.
1475 BC Istanbul completes spearmen and begins working on settlers. A citizen is moved from the 2 Food, 1 Commerce grassland to the 1 Food, 2 Shield, 1 Commerce forest next to the river. Edrine completes spearmen and start work on archers. The Istanbul spearmen head towards Iznik on the road.
1450 BC Iznik completes spearmen and begins work on archers. The Istanbul spearmen move west twice and south once. The worker completes the mine and moves south.
1425 BC The workers begin a road and the spearmen head south.
1400 BC The spearmen head south.
1375 BC The workers finish the road and move southwest. The spearmen head southeast into Uskudar. Uskudars production is changed to archers. We discover Alphabet and begin work on Writing.
1350 BC Istanbul completes settlers and begins on spearman. The settlers are sent with a spearman escort along the road to Iznik. Edrine builds archers and begins work on settlers. Bursa completes archers and begins work on workers. Both new archers head along the road to Iznik. The worker begins building a road.
1325 BC The settlers move two squares west and one south. The archers continue along the road.
1300 BC The Aztecs have built a city on my intended spot. An Aztec warrior that stumbled onto my road blocks the archers path. The archers wait for one turn, as their movement will be faster if they use the road next turn. The settlers and escort move into Iznik for protection. The worker completes a road and begins work on a new mine.
1275 BC Iznik completes archers, and begins work on a temple. The archers head one square northeast and join the other archers that make it along the road.
1250 BC The archers head south and southwest twice. The spearman escort moves south to guard the workers from a nearby Aztec warrior. Bursa completes a worker, which moves south and begins constructing a mine. Bursa begins work on a temple.
1225 BC Istanbul completes spearmen and begins work on new archers. My band of three archers heads southwest again. The spearmen fortify on the worker square.
1200 BC Edrine builds settlers and begins work on spearmen. The settlers move with a spearman escort towards Istanbul. The three archers move southwest again into Aztec terriroty. The Aztec city is defended by archers at best. The southern workers complete the mine and along with the spearmen escort move southeast one square. Izmit produces archers and begins work on workers. The warriors protecting the iron move towards Uskudar.
1175 BC The Aztecs told me to get out of dodge, but we refused and are at war. The archers in the city didnt attack us. The warriors took a step closer to our archers and are within one square. Our first archer destroyed the Aztec city and got promoted. The second killed the warrior and also got promoted. The third moved southwest to the Aztec city square, providing cover for the first archer, who took a bruise. The settlers in Iznik moved south, and the spearmen protecting the workers moved northwest to occupy the same square. The workers began constructing a road. The warriors moved into Uskudar for extra defence.
1150 BC The archers that killed the Aztec warriors moved west towards the others. The other two fortified where they are. The Bursa workers finished the mine and began a new one to the southeast. The settlers moved southwest. The other settlers near Istanbul continued along the road to Iznik.
1125 BC The settlers near Iznik moved southwest again. The others moved south and southwest twice, putting them nearby. The archers moved into a stack. The workers finished the road and moved southeast. Istanbul produced archers, which are moving towards Iznik. Istanbul will produce more settlers, but looks likely to grow first (causing disorder). I moved a citizen from the grassland back to the forest as before. Iznik will not finish the temple in time either, so one of the citizens working the grassland will become a scientist.
1100 BC Izmit produced a worker and began work on a curragh. The worker headed north one square. The Istanbul archer moved west twice and south. One settler group went south, and the other headed west.
1075 BC We discovered Writing and began looking into Mathematics. The Istanbul archers moved southwest twice. The settlers moved south and west as before. The Izmit workers began a road. Edrine finished spearmen and began work on workers.
1050 BC Uskudar went into disorder (oops). The Istanbul archers headed west. The settler bands continued their movement. The southern band went southwest and the other group went west again. The southern group has seen some spearmen, so the stacked archers moved south. The Iznik workers moved northwest three times, and the Bursa workers headed northwest twice. In order to complete Bursas temple before the city grows, I moved some citizens to a forest.
1025 BC The Aztec spearmen (and settler) moved north past my archers, putting them at risk (should have fortified!). My settlers founded the cities of Aydin and Antalya. Both cities began constructing Walls (Im here to stay!) One band of archers defeated the spearmen and captured the settlers. I moved the new slaves east and the other two archers southeast into Antalya. The Istanbul archers moved west, taking them close to Aydin. My Izmit workers finished the road and moved northwest. The Iznik workers began building a road, which will connect Aydin to my empire.
1000 BC The Izmit workers began to build a road. Edrine completed the workers and began work on a temple. Istanbul completed settlers and also began to build a temple. The archers near Aydin moved in for defence and the others are heading in that direction too. The Aztec slaves began building a road. The Istanbul settlers headed northeast, north and northwest. The warriors to the north will provide defence, so no escort is being sent. The Edrine workers moved northeast. I also made peace with the Aztecs. It looks as if they would have parted with the city of Malinalco too, but I had no idea where it was or what it was like. I also felt that a better deal for them may improve relations a bit more.
