The GOG Preservation Program 
ensures classic games remain playable on modern systems, even after their developers stopped supporting them. By maintaining these iconic titles, GOG helps you 
protect and relive the memories that shaped you, 
DRM-free and with dedicated tech support.
Although these pioneers of the RTS genre are leaving our store, as part of the GOG Preservation Program, we are committed to maintaining and updating them so they’ll live forever in your library. Both titles introduced groundbreaking mechanics and marked the beginning of Azeroth’s story, making their preservation essential.
When a game has been played relentlessly for 25 years by gamers all over the world then calling it "iconic" and "timeless" still isn't enough. The magic of Heroes of Might and Magic 3 is unmatched and responsible for endless nights spent on its hot seats. With the GOG Preservation Program, this magic will continue to enchant us forever.
A game that defined an entire genre, inspiring countless titles, and yet, after all those years, remains one of the best games ever created. The original Diablo is a legendary masterpiece by legendary creators, and the GOG Preservation Program will make that legend live forever.
A game that changed the face of survival horror, Resident Evil set the highest standard for atmosphere, tension, and unforgettable moments of fear. It's still one of the greatest gaming experiences ever created. We 've brought it back to you and the GOG Preservation Program will keep its legacy of terror alive for generations.
Not necessarily. For a game to qualify for the GOG Preservation Program, our team must run it through many quality tests. If these tests fail, our team updates and improves the game until it matches our quality standards. Only then, we stamp the game with our Preservation Program and grant it Good Old Game status. There is a long backlog of classic games available on GOG that may already qualify for the program, but our team has not been able to confirm that yet. We aim to support as many games as possible, but it's not always entirely up to us.
We test and update the games so they work flawlessly on the most popular PC configurations - now and in the future. The PC landscape is constantly evolving, with changes like new Windows updates or graphics card drivers occasionally affecting compatibility. If you encounter any issue with a game in the program, please contact our customer support so that we can verify and fix this issue for everyone. This helps us maintain the quality of those titles.
The GOG Preservation Program is currently Windows-only. Our priority is to preserve as many games as possible under the Program, before expanding to other operating systems.
No. The program may include any game that needs maintenance and that we can commit to maintaining ourselves, even if it was released just a few months ago.
No, because GOG can’t take over the responsibility for the game’s quality from the developer, as it is expected to be updated and expanded with DLCs, new editions, etc.
For a game to qualify, our team must run it through many quality tests. If these tests fail, our team updates and improves the game until it matches our quality standards. Only then will we stamp the game with our Preservation Program and commit to its maintenance. There is a long backlog of games currently being evaluated. We want hundreds of games to be stamped by the end of 2025.
We never want a game to be removed from the GOG Preservation Program, and at the time of this writing, we don’t see a reason it should happen.
The GOG Preservation Program aims to preserve the original game and make it playable on modern machines. This means being very careful with any modification that might alter the original experience. We also want to avoid passing the responsibility of maintaining the game’s quality on to the community, as it wouldn’t be fair to you.
Games in the GOG Preservation Program remain part of the initiative even if they are no longer available for sale. We will continue ensuring their compatibility with modern systems.
