True on the traffic. Sure, the game isn't perfect. However, one of the successes of Skylines has been the honest tone and communication with the developers. There's a sense of confidence that the game will be supported and improved over time. This didn't exist with Sim City 5, what with the always-online drama, the inability to play the game well for several months after release, and the early focus on producing large amounts of paid [overpriced?] DLC.
I think a lot of the demerits in Skylines exist within the core game of Sim City 5. The problem is, as I see it, that the obvious marketing (buy more things, here, get this Nissan leaf station for your town for free!!!), and the lies (it has to be online, simcity wouldn't work any other way), made players unwilling and unable to forgive simcity's foibles in the game. It was obvious people were being treated like a resource to be extracted, not a demographic of people who want to have a need fulfilled.
All games have failings, how many failings, and the degree people are willing to forgive them is the thing that changes.
I think after the anger of simcity 5, people are willing to forgive a lot of foibles, and despite that, Skylines doesn't seem to have many, it's pretty solid.
