I also love city building games and have played sim city, sim city 2000, sim city 3000, sim city 4, and finally cities:skyline. Transport is the most important part of Cities: Skyline indeed, and that's what makes it fun! I was inspired by you and made a post on the city that I built in Cities: Skyline a while ago. Come check it out!
