I'm a fan of a few different ones. I like Banished, Aven Colony and Cities: Skylines if we're talking newer titles. But my all time favorites is probably some of the ones from Impressions Games. Pharaoh, Zeus and Emperor. Don't blacklist me, but I also did like SimCity 5, although I did agree with most of what people were complaining about on that one.

I'm only getting back into city builders myself, but I loved playing them as a kid/teenager in the late 90s/early 2000s - I used to play the old Sim City games and Age of Empires (was that a city builder, or strategy game? not sure...). I also liked the first Roller Coaster Tycoon, which is somewhat like a city builder. In the last month I started playing Tropico 4 and I've been enjoying it. I'm going to beat the campaign without any of the expansions, then try the expansion campaigns. I also have my eye on Cities: Skyline and the Cities in Motion games.

I used to love Sim City as a kid! I thought Cities in Motion 1 was great in theory - but clunky. The Tropico series is awesome, and I'm working on 100%ing Banished.

Sim City - first one :) Tried to play it again but my eyes couldn't handle it xD
