With Cities Skylines 2 struggling to find its feet amid a host of early problems, now feels like a good time to revisit the series that preceded it. EA's 2013 soft-reboot that was essentially SimCity 5 landed to widespread negative reactions, opening the door for Colossal Order to step in as the go-to realistic city-building simulation. But prior to that fall, the series had long been the epochal city builder, and if you missed it at the time or fancy revisiting it, you can get the best of them all, SimCity 4, at a big discount right now.
