A few options would be nice for the generated terrain just to add some variation.
- Number of towns / cities (with upper limits I guess)
- Number of industries
- Percentage of water
- Percentage of forest coverage, just because more trees look good.
- Coastal Map’s
Real flat terrain isn’t something I would desire personally, but I am guessing that has been requested due to ‘collisions’ and other line placing issues, which if tweaked / fixed would be better imho.
