Sorry for my inexperience: how can I use the OCN? How the number is calculated?
(example: Chieftain-Communism-Forb.Palace & Sec.Police HQ-Huge map-Commercial= 333 cities!!)
Alternatively: where can I find in Civfanatics this infos?
Thank you in advance!
The OCN refers to your optimal city number. If your empire has more cities than your OCN, the corruption level gets higher in cities ranked over your OCN. Therefore it is better to have the highest OCN possible, as it allows you to have a higher number of cities that are productive.
OCN formula for your empire:
Nopt = OCN * (L/100 * (1 + c + Gr + Gp*Nwe)
where
OCN is the optimal number of cities for the map size,
as found in the editor
L is the percentage of optimal cities for the current
difficulty level, as given in the editor
Nwe is the number of active Wonders in the empire with
the reduces corruption ability
(Forbidden Palace, SPHQ)
c = 0.25 for a commercial civilization,
0 otherwise
Gr = 0.1 for minimal or nuisance corruption
2 for communal corruption
0 otherwise
Gp = 3/8 non-communal corruption
3 if communal corruption
For more details on distance and rank corruption, the reference is Alexman's article

Note: The OCN works very differently for communism vs all other governments. Because of the communal corruption, the OCN has to be higher, hence the different values in the formula.
