Dealing with Corruption
-------------------------------------------------------------------------------
There are a surprising few ways to deal with Massive Corruption that occurs
in Huge maps (or even large empires on the smaller maps).
Each map size has an "Optimal City Number." Once you build more cities than
that number, you get more corruption in EVERY city.
Tiny 12
Small 14
Standard 16
Large 24
Huge 32
That isn't to say you shouldn't build more cities than the "optimal," just
that you'll have to deal with the consequences.
Difficulty level also influences corruption. Under the easy options, more
cities can be at "optimal," under the harder options, fewer.
Chieftan 100%
Warlord 95%
Regent 90%
Monarch 85%
Emperor 80%
Deity 70%
So, logically, a Deity Huge map would have only 22 optimal cities (32 * .7).
