First, about that option: it's on the "graphics" tab, called "detailed city info".
Now, some thoughts on further development, and a dotmap:
1.
Scout the area NE of Moscow. Likely there'll only be tundra, but maybe some resources. And our scout has nothing else to do, does he?
2.
Connect Moscow and St. Peter. Rivers do act as roads for connection, but the roads have to go to a tile adjacent to them ("fresh water"). Diagonal is not enough (and yes, I know it looks like the roads connect)! This also holds true for Novgorod, which won't be connected once we road the pigs.
By connecting St. Peter, we get another health for Moscow from the fish. I dunno if it's advisable to grow further, though.
3.
Do we need barracks in St. Peter? I'd go for lighthouse and get big-time research there. Irrigate FP now for growth, later get cottages. This isn't a production center, but it can get huge amounts of commerce thanks to our trait bonus and the sea.
4. Probably not in the next 20 turns: get a galley around the southern peninsula (behind the peak), and if possible drop off a land unit to scout.
On more cities: I'm not concerned too much about maintenance cost. Thanks to our trait bonus, we should get enough money in (mostly from St. Peter). Also, at the moment we don't need research that bad - after all, we got a whole continent to fill! I'd probably stop expansion when we get to 50 or 60% research, but go on as long as possible!
With this in mind, here's the dotmap:
Comments:
The other numbers are mostly in the order in which I thought of them; I think the 5th city should either be #5 or #7.
"next city" gets good production from forests and horses, I think that's best to complement what we have so far. Also I think it makes good use of the land up there, has enough food (horses, clam) and later two hills to mine (one under forest). Depending on what our scout finds in the north, this might need an archer or two for defense against barbs.
I'd prefer putting #6 where I placed the marker, since it'd be difficult to reach/improve the land south of the peak, but if that peninsula is really big (scout this with a galley first), we might want a channel there.
If #6 goes to the lower position, #5 might also go one further south to the plains tile; although the difference isn't so large I think (in one case #5 is stronger, in the other #6 is).
#7 is fresh water, but not wasting a floodplain, and can be another huge-growth city (with some production from two desert/hills).
#8 should probably be founded after #6 and #7 are in place. I wanted to have it on a river, and use the land south of #7, west of Novgorod, that's why I came up with this position. #10 would probably be between #6 and #8.
#9 is on the coast, gets both the iron and sheep, and has some decent tiles to work (while not wasting any where it's built). This one might also look good one further to the west, if we get another city (#11) north of Moscow.
My preferred order (subject to change on findings by galley in south, scout in north):
"next city"
#5 IF WE KNOW about the channel, either there (no channel) or one to the south (channel)
#7
#6 in the respective position
#9
#8
what are your thoughts?
