OpenTTD

OpenTTD is a free, open-source business simulation game that has been in continuous, active development since its Steam release on April 1, 2021. The project ships major numbered releases on a consistent annual cadence: version 12.0 arrived October 17, 2021; version 14.0 on April 13, 2024; and version 15.0 on January 1, 2026. Each major release introduces substantial new features — version 14.0 added a new ship pathfinder, vehicle unbunching, and social platform integration, while 15.0 brought infinite water island maps, river wetlands, bridges over stations, and road waypoints. The team is now actively developing version 16.0: beta1 shipped June 25, 2026 (introducing backwards-driving trains, improved map generation, and numerous other features), and beta2 followed on July 12, 2026 with additional fixes and the doubling of the maximum vehicle limit. The store description explicitly states "OpenTTD is under ongoing development," and a bug-fix post from April 4, 2026 confirmed the team was "hard at work on features for OpenTTD 16." In March 2026, there was a notable distribution change: OpenTTD is no longer sold as a standalone product on Steam and is now bundled with Atari's re-released Transport Tycoon Deluxe. A developer statement on March 19, 2026 clarified this reflects a mutually agreed compromise, that the OpenTTD project "retains its full independence," and that "we will continue to deliver new versions of OpenTTD to all platforms, including Steam." Existing Steam owners continue to receive updates normally. This change has not affected development activity, as evidenced by the continued release of 16.0 betas in June and July 2026.
