1. More land tiles, and please not behind a mountain range (so on the right side) so it fits better with the city you build.
2. 4 sided cars so we can have cars on both side of the road and not just on one side.
3. Ability to make the river you add fit with the sea, now there is always a beach in between.
4. Ability to remove part of the mountain range between springfield heights and the rest so it fits better with your whole city, or just a deco to put over the mountain range like a park, road etc.
