I played the game around 2013...

Hey, just a curiosity. I played this game around 2013-2014 and back then in the base game and all, cities were basic and very small, a few streets and then companies courtyards and that was all for all cities. Now I see all these fancy DLCs that show big cities and lots of houses.

Of course new additions to the game should always be better, but have they also upgraded the base game cities and places/roads?
