Steam is the free digital distribution platform that is powering the game. To learn more about Steam click HERE. We chose Steam to power all versions of our game so that we could create one unified RollerCoaster Tycoon experience for all players. If you don’t have it already, it will automatically install when you install the game, and is completely free. Additionally, utilizing Steam allows us to offer things like Cloud Saving, Steam Controller Support, and Steam Workshop, all seamlessly integrated across Windows and Linux (as well as Mac post-launch).
