849 strategy games on Steam with co-op or multiplayer, ranked by how many people are playing right now and how well they review.
Strategy games are where a weeknight turns into a Saturday. Civilization VI and Stellaris will happily eat a whole evening for two, Age of Empires II still fills lobbies twenty-five years on, and Hearts of Iron IV or Europa Universalis IV are the choice for pairs who like their wars with spreadsheets. Co-op is better represented than most people think: RimWorld and Cities: Skylines gain multiplayer through community mods (both are in the catalog with the mod named), Total War: Warhammer III has a full co-op campaign, and Anno 1800 lets two people run one economy. The hub ranks by players online and rating, and splits into real-time, turn-based and grand strategy, builders and tower defense so you can pick a pace first and a game second. Tip for pairs with mismatched skill: pick a co-op campaign over a versus match — nobody enjoys losing to their friend for four hours.
Narrow it down: Real-time strategy (398) · Turn-based & grand strategy (308) · Builder & management (61) · Tower defense (59) · Auto battler (23)
