A 30-year-old transport simulation game just became the unexpected flashpoint in how copyright ownership shapes free software. Atari acquired the rights to Transport Tycoon from Chris Sawyer in November 2024, stating it had a "long-term plan to preserve and expand this classic sim." This week, Atari delivered: it launched an updated port of Transport Tycoon Deluxe on Steam and GOG, priced at USD $10 / GBP £8.50.
That's good news for preservation. Transport Tycoon Deluxe had been abandonware for a good while, accessible only if you happened to have a physical copy or were willing to commit e-crimes. For nostalgic players and newcomers curious about the original, the re-release means a legitimate way to own what many consider one of the finest simulation games ever made.
The complication: OpenTTD will no longer be directly available as a standalone game on Steam; it can instead be obtained as part of a bundle alongside the original Transport Tycoon Deluxe, according to the development team's statement on GitHub. The same change applies to GOG.
OpenTTD is the story here. It's an open source simulation game based on Transport Tycoon Deluxe that attempts to mimic the original game as closely as possible while extending it with new features. First reverse engineered and released in 2004, it has become the de facto way to play the game on modern machines, thanks to extensive additions including multiple map sizes, support for many languages, custom AI, downloadable customisations, ports to several widely used operating systems, a more user-friendly interface, and multiplayer for up to 255 players. The game has been free on Steam for five years, building what the development team describes as an incredible player base attracting lots of new players.
This is where the tension emerges. New players will need to purchase Atari's new version in order to access OpenTTD on Steam and GOG. However, it does not affect getting OpenTTD directly; only the GOG and Steam pages are being changed. Users who already own OpenTTD are unaffected; they will continue to receive future game updates and it will remain available in their library to re-download.
The move reflects a genuine legal and commercial reality. Atari now owns the Transport Tycoon trademark and original code. OpenTTD operates in a grey zone: it is genuinely open source and does not require any original game assets to run. Yet it exists in direct competition with Atari's product, and platform operators like Steam and GOG ultimately defer to intellectual property holders when asked to restructure their listings.
From Atari's perspective, bundling both games is defensible. Atari acquired the rights from Chris Sawyer back in 2024, and at the time mused that it would use ownership to "expand digital and physical distribution, potentially develop new titles or content, and explore brand and merchandising collaborations as part of a long-term plan to preserve and expand this classic sim." Giving players access to both the original and the superior fan remake is reasonable; asking new players to purchase the original to legitimise the re-release is a standard business move.
The consequence, though, tilts the playing field. Casual players discovering Transport Tycoon for the first time will now encounter a paywall between curiosity and play. For a free game that has attracted millions to the series, that friction matters. The game itself will still exist freely available on the OpenTTD website; it is simply harder to find on the platforms where most people search for games.
This is what intellectual property rights look like in practice: not dramatic or sinister, just the ordinary exercise of control by a company that now owns a sought-after thing. Atari is not acting unreasonably. The open-source community built something good from the original. And somewhere in the middle, new players will have to make a choice about whether to pay for access to a 1995 game, or hunt for the free alternative online.
