Really one of the most fun coop games I've played. Sometimes a bit random and with a bit tricky controls, but it's always fun!

While there might be some DLC which offer more exciting features, Green Cities really feels like a great extension of the main game - offering a big variety of alternative buildings for nearly every category (usually with a tradeoff between additional costs but decreased pollution/electricity or water consumption). I would not want to play another round without Green Cities enabled.

Fun DLC which allows you to create your own parks. While they are many buildings/objects to choose from to build three different types of parks, it can get a bit repetetive.

Unfortunately, the snow mechanics only work on a few selected maps (and on them, it is always winter). The main reason for buying the DLC actually are the trams (which are superior to busses in every way).

This is THE DLC I can't play without anymore. There are way too many QoL improvements (like the combined stations/hubs, the combined roads,...).

If you only want to buy a single DLC, it should be Mass Transit!
