Well I had a little look at the game...The number in front of each city's name is its current size.
9 Olympia
current - Bank
Next - Most likely a wonder (just 39 turns to complete Hoover Dam and thats not including caravans), Sewer system in the future.
Note: Clean the polution!
8 Hippoville
Current - Factory
Next - Bank / University / Freight
11 Dreadtown
Current - Factory
Next - Sewer system / bank
10 Cornmaster
Current - Bank
Next - Factory / Sewer system/ freight
10 Dellville (has low production at the moment)
Current/next - Market, however I would like to see this changed to a factory or an offshore platform, which could then be rush build to improve production. Then the market could be built quickly and so could a library and possibly freight
6 Viroconium
Current - Freight
Next - Freight / Possibly some military units
5 Spice Haven
Current - Temple
Next - Freight / Some other imrpovements could also be built
2 Renmark
Current - Riflemen
Next - Diplomat / City walls / Riflemen
6 Dukeshire
Currrent - City walls (could be rush built)
Next - Riflemen / Diplomat / Library / Cavalry (If we are going to attack the Romans in the near future)
