Not out of the box — but the OpenRCT2 mod makes it co-op. RollerCoaster Tycoon® 2: Triple Thrill Pack is a builder & management game released in 2014, 89% positive on Steam (5,445 reviews), with 96 playing right now. $9.99 on Steam.
The open-source re-implementation of RollerCoaster Tycoon 2 adds real multiplayer: build one park together on a server. Steam lists RollerCoaster Tycoon® 2: Triple Thrill Pack 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.
This compilation includes the entire RollerCoaster Tycoon 2 series, with the original game as well as the Time Twister and Wacky Worlds expansions.
Steam tags: Simulation, Management, Classic, Sandbox, Strategy, Singleplayer, Building, Economy
