Cities in Motion 2 came out just a few weeks after SimCity and quickly became its rival. Luckily for the developer, SimCity was suffering controversy and criticism by this point.
The game stands on its own merits, however. Instead of simulating a city's development and growth, you manage mass transit and roads. Accordingly, the city grows dynamically in response to the transportation systems you provide.
If you love micromanagement and are interested in mass transit, you'll get a kick out of scheduling traffic timetables, planning freeways, running trams, and deciding if your city really needs that expensive ferry terminal.
You can find Cities in Motion 2 on Steam for $19.99.
