Hadn't played Cities skylines since launch, and at some point I must have bought the majority of the DLC, so have started playing again. Really enjoying it, the DLC have added some interesting stuff. Granted it probably should have been in the base game, but the Industry and Mass transit stuff makes it a lot more interesting, pls the others (I don't have the disasters, campus or sunset harbour DLC though).
Love the slow paced nature of it, and some of the mods are great. The realistic populations mod is interesting, although it does show up the weakness in the game in regards to traffic management/AI.
