61 builder & management games on Steam with co-op or multiplayer, ranked by how many people are playing right now and how well they review. Part of Strategy.
Builders are the genre where 'one more turn' becomes 'it's 2 am.' Anno 1800 and Tropico 6 have proper co-op — two players, one economy. Cities: Skylines and RimWorld are single-player on Steam but have mature community multiplayer mods (CSM and RimWorld Multiplayer, both listed on their pages), and Kingdom Two Crowns is a gorgeous two-player co-op from the start. Stronghold Kingdoms and Kingdoms Reborn cover the persistent, slower end. These are long games; they suit a pair who will meet in the same save every week. Ranked by players online and rating, so you can tell which ones still have an active community for mods and multiplayer.
