Great game with lots of depth
I've previously played OpenTransportTycoon and loved the great detail of the game. In searching for an alternative I stumbled upon Cities in Motion. After playing the Demo i bought the game and I have to say, i'm impressed! It does take some time to get to "know" the game but it's a quite realistic simulation of how real life transportation within cities is.
If you're looking for some in depth Transport simulation, look no further!
