Havent done an awful lot so far, almost at 7k pop and taking my time.
Having watched people like Quill18 and their intersections, i have to say its rather satisfying creating a clean and functional area. Its not super easy, but if you take a moment to think about things and what would look nice and tidy too, its not hard to do it right. Yeah, you can accept the first route that works but its often ugly.
Im now trying to work to 8k for the dam, theres a cracking river next to the start location on Black Woods, and i plan on making full use of it.
Havent had any issues, and very happy so far. Will take a good while before we see new issues i suspect, few people have hit significant population numbers (200k+).
