I unironically play this game regularly, it just keeps me coming back !! I really enjoy the activity of building up the many towns in a region and bouncing between each one.
I own Cities Skyline too, so if I really wanted to play something better I could, and sometimes I do. I like that you can be a perfectionist in that game (being able to edit each individual street name comes to mind) but Sim City 2013 serves a different purpose to me. It's nice to play with the more basic mechanics because it makes me think outside the box... theres just nothing like aggressively building up a town and then not building a university and then building a powerplant so all your high-school diploma sim residents have to try and not destroy the entire town. Just kidding... mostly.
I do struggle to make sufficient funds in SimCity 2013 which is often annoying but I am also often impatient so maybe I am the problem c:
