Not out of the box — but the Sims 4 Multiplayer (S4MP) mod makes it co-op. The Sims™ 4 is a farming & life sim game released in 2020, 87% positive on Steam (170,727 reviews), with 25,276 playing right now. Free on Steam.
Real-time shared households: build, cook, set fires and earn Simoleons together. SimSync is the other well-kept option. Steam lists The Sims™ 4 as single-player, so it won't show up in Steam's own "games we both own" view as something you can play together — Ready Up counts it anyway, marked "Via mod", and you can hide mod-only games with one filter if that's not your thing.
