Turn 0/4000 BC: I settled in place, and the immediate surroundings near the capital looked somewhat like this:
Riverside grassland hills to the south, and a little further south there is a floodplain tile visible. That direction looks promising!
First build: worker! First tech: Agriculture!
Turn 2/ 3920 BC: That floodplain tile got me curious to explore towards that direction, and it seems that location is even better than I thought!
2 floodplain tiles and a riverside gold mine... that place is looking like my commerce city is gonna go there. Maybe as a 2nd city, or maybe a 3rd one, but definitely not past that. 2nd city may have to be settled to grab a more strategic resource, even if it means its commerce or food may not be all that great.... but more exploration is needed!
Turn 6/3760 BC: Further south is looking more like a smaller peninsula than a larger landmass. Considering that I haven't met anyone coming from that direction, I figure it is most likely a dead end exploring that area with deserts mixed in, so I decide to explore towards the west instead.
Turn 7/3720 BC: We meet our first AI in the game, confirming that we are NOT alone! ^_^
Well, hello Lizzy! ^_^ Have I ever told you that she is the most awesome leader of all time in history? Okay... I am biased, but seriously though... Lizzy as an AI isn't too bad to deal with. Since she is the first contact, I assume she is gonna be my nearest neighbor, which means... a soft target for my Praetorians! However, she did come from the north beyond the jungle, so that might mean that getting to her may not be as easy as we would hope.
Turn 8/3680 BC: Buddhism is founded in the far away land.
Turn 9/3640 BC: Agriculture is finished! While deciding what to research for the next tech, my scouting warrior reveals what might make Fippy sing in high joy! ^_^
Turn 11/3560 BC: 2 turns into researching Bronze Working... since I figured I wanted to see where copper is sooner than later, and I also figured early chopping may be in order. Anyways, at this point, the exploration of the map nearby reveals this much information as a whole:
I like exploring in circles around my capital first, to find the nearest and the most suitable 2nd city site, and so far, what's looking ahead looks promising. And now that the stone has been revealed, I am sure Fippy would be very happy! ^_^
Anyways, I am eyeing either the red or the blue square I marked here...
The blue square looks like a no brainer.... the red square...? You might say that it lacks food and commerce there, but this place can still work 4 tiles (plains cow, the stone, the grassland 1E of the cow that can be farmed, forested grassland hill mine 1SE of the cow) without food problems, and with a plains hill city tile, the hammer production would be quite good.
Bear in mind that the water tiles 2N of the western corn is a fresh water lake. Settling out towards that way with the western corn may be too far away for a 2nd city at this point, but having that stone city can help accelerate expansion that way.
Of course, all this can change if copper or horse pops nearby, but assuming that they are not nearby a reasonably close site for a 2nd city, I think one of these 2 places make the most sense for me.
