Am I missing something? in your earlier screenshot you had some core cities CxC, in the screenshot I commented on they where all CxxxxC, Most people here would advice CxxC.
And on top of that, i think the correct spacing is a pretty delicate but very important decision. Be carefull about it.
-In somewhat longer games, i want 12 usefull tiles per city (deserts and large amounts of mountain are not counted). No more are needed since i won't build hospitals even if i invent every tech available.
-If i expect short game, that should end in the early AD's, 10 tiles per city will be enough for my core towns.
Very little space to start with may also make you go for a tighter placement.
When planning my new cities, i actually
count the average number of tiles per city my empire has. I do not yet mentally assign tiles to the city, it will always be possible to micro manage the tiles between the cities when needed just as long as the averag is ok. Of course, keep in mind the cultural expansions you are planning to get and where not.
In C3C, cities thus don't need to be in any specific pattern they just have to be somewhat evenly devided over your empire, other than that, you just pick the best spots that allow for the needed tiles per city.
In PTW, the number of tiles you want per city decide the amount of cities you put into your CRP ring. What crp rings to use depends mostly on your surroundings and the space available. CRP4 is prefered.
If you space your cities wider than needed, you are wasting land that could be used and you are having more corruption in your core cities than needed.
That hurts.
If you space your cities closer than needed, your cities cannot grow to their target size 12. This also hurts since these are your low corrupt cities and you aint gonna get back production you lose because of this in other cities. Those are corrupt. This however only hurts you by the time your cities grow to that size. Before that, the closer spacing actually benefits you because of the lower distance corruption.
If your game does not last beyond your cities growing to size 12, the optimal target city size is just smaller than what they could become.
If you expect to win in the early AD's, your cities
could grow to size 12 if you want, since however the production lost by not maxing your city size is countered by the earlier* benefits of tighter spacing, size 10 is often a good target. Smaller even if you expect extremely short games like tiny pangea maps.
Point is, keep corruption low by not spacing them too wide, don't let your cities maximise their size more than about 20-30 turns before you finish your game.
If you plan for a long game, 14+ tiles per city is no good. 11- tiles per city is no good either. Count them and make it 12. (a few extra tiles over your whole empire won't hurt, it makes micromanagement and swapping tiles a bit easier)
*Also note, earlier costs or rewards are more costly or valuable than later in the game. What you produce the last 10 turns often has zero influence on your finish date, what you produce the 10 turns before those only little.
Edit: Another important note, espescially for PTW where you use crp: Always make sure you give priority to the lowest corrupt town. This can matter in your city planning. It doesn't really matter a lot what land those corrupt towns have. When you are planning to place corrupt towns, count the land between the good and the corrupt towns as 100% designated for the good town. If there are semi corrupt towns, the land between the good and semicorrupt is for the good town, the ground between the semi corrupt and fully corrupt town is for the semi corrupt one.
