For fun, I decided to calculate what real life cities would be in civ using the math from the SDK (hopefully I am correct ):
Tokyo:42 (entire Canada would be pop 41)
Mexico City: 33
New York: 33
São Paulo: 33
Mumbai: 33
Delhi: 31
Shanghai: 30
Buenos Aires: 29
Karachi: 28
Los Angeles: 28
Rio de Janeiro: 28
Beijing: 27
Moscow: 27
Paris: 26
Chicago: 25
London: 25
Hong Kong: 23
Bangkok: 23
Lahore: 22
Miami: 21
Madrid: 21
Philadelphia: 21
Toronto: 21
Barcelona: 20
Boston: 19
Sydney: 19
Singapore: 19
Houston: 19
Atlanta: 19
Washington: 19
Detroit: 19
Montreal: 18
Monterrey: 18
Berlin: 18
San Fransisco: 18
Rome: 18
Edinburgh: 8
All of America: 90
If every member in this forum joined up into a city, it would be pop 5
If you have 30 pop and lose 1, that's the equivalent of losing over a million people!
