Just like in real life, the cities in Cities: Skylines 2 offer a lot of different public transportation options. Players can use buses, taxis, trains, and even subways to help bring citizens to where they need to be. It not only makes the cities feel a bit more realistic, but it also helps alleviate the traffic problem immensely. And while the game may have improved the entire system, it also left behind one of Cities: Skylines most unique transportation options.
