Our World, 4000 BC
And the save is
>>HERE<<.
I rolled several startups before I got this one. I was looking for quick access to fresh water, at least one luxury and one bonus grassland. This was the best overall. Even though this is only Monarch level, and we get two content people per city, citizen happiness will become an issue when we grow to size 3. With the furs connected, the city can grow to size 4 before we need to worried about cranky citizens.
Initial Twenty Turns
I would like to encourage everyone to play the first twenty turns. But before we do that, let's look at our start and try to determine some basics; such as build here or move, what to build, what to research, where to move the worker, etc.
Where to Build
Usually it is good just to build whereever you are, but here I don't know. I think we might be better off moving to a hill, most likely the one to the SW and making that our capital city. This leaves the plain free to be mined or irrigated and makes the hill more productive (2 food, 1 shield) than otherwise. It is also a better defensive position (just in case). It may also be a coastal tile; the screen shot hints at that anyway. And it is still adjacent to the furs and the BG across the river.
Moving 1SW puts the flood plain out of our initial 9 tiles, but we should reclaim it in the first border expansion.
And now I must confess some ignorance. I did not stop to check to determine what advantages the AGI trait gives us.

Can someone explain what that trait does for us and how it affects our start up?
Not being familar with the AGI trait, I can't comment on what to build or research, but those who know more about it certainly can.
