After completing that, you’ll wait around for your population to grow before laying down a bit more housing and repeating the process.
This makes the early goings of each city play out exactly the same, having you focus on optimizing your spending to lay out just enough residential zoning, electricity, and piping to generate more revenue. The game is also hamstrung by its milestone system, which demands you reach a certain population number to unlock further building options. District painting also doesn’t let you add to already established districts, instead creating entirely new ones that can overlap with previously plotted areas. You’ll have to scroll to each individual piece of road or building you want demolished to make room for whatever your plans are. Maybe these are in the PC version (I’ve never personally played that), but batch deleting is impossible when making renovations.
That isn’t to say everything is perfect because Cities: Skylines does miss a few key features that would greatly improve the experience.
