Most of the things on that list worked fine in the original Sim City. You know, the one from 1989.Patch 2.0 in April:
Residential Tuning: Residential-only cities have failure state.
- Buildings are prevented from going up in density when they don't have power or water.
- The amount of happiness gained from low taxes, police, fire, and health outreach has been lowered.
- Fixed some cases where buildings would not go abandoned when they should have.
- Higher density residential buildings are no longer blocked from going abandoned due to not having enough money.
- Happiness from low taxes does not double up every time it is given.
- Losing happiness due to not having a job is more impactful.
I kept meaning to go back and tinker with it when they added elevating/sinking roadways.
Oh, and lol at the stealth release of an expansion!
