Play Cities: Skylines

The sequel with better roads and a rough launch.

Zone, tax, build a stadium and watch it burn; the city builder that defined the genre.

Build a park and lay a coaster track piece by piece; Chris Sawyer wrote almost all of it in assembly.

RollerCoaster Tycoon reborn with a coaster editor; Frontier.

Salt the chips, water down the drinks and watch the queues; Bullfrog's management sim.

More scenery, a track designer and the version the community still builds in.

Regions, terraforming and a traffic simulation people still argue with.

The 1989 original: lay down three kinds of zone, watch the traffic, then send a monster through it.
