Title: Allow making cities smaller than normal.

In addition to turning New England into New York, you can now instead turn it into New Hampshire by lowering the city sizes below the default of 4.

3 = smaller cities, still town-sized
2 = tiny villages
1 = New Hampshire mode: Nothing but trees, roads, and very occasional buildings.
