On Monday Dec. 9, 2013, classic and modern (but mostly classic) downloadable video game service GOG.com (formally Good Old Games) announced a new guarantee that every single game on the site will run properly, or your money back.
If your computer meets all of the minimum specs for the game, and their support team cannot resolve the problem, or fix “game breaking bugs,” then they will return what you paid. In return, the game will no longer be available in your GOG.com library.
The need to play older games on modern computer operating systems (OS) is one of the main reasons GOG.com was conceived. When most new OS release, such as Windows Vista and OS X Mountain Lion, gamers often have to say goodbye to many of the terrific titles in their collection because they are no longer compatible. Even worse, some of the games that should be compatible still can't be played because the digital rights management system (DRM), software integrated to prevent illegal/unauthorized copies of the software, isn't compatible with the current OS, blocking the game from running.
Then in August of 2008, GOG.com launched, and brought back an amazing collection of classic computer games, totally compatible with modern operating systems, completely legitimate, easy to install, and 100% DRM free. From hard to find titles like Waxworks, and the original Alone in the Dark series, to historic classics, such as the King's Quest series, Phantasmagoria, and Duke Nukem 3D. Then in March of 2012 they began offering more modern games, including The Witcher 3, Allan Wake, and Retro City Rampage.
Now, to stop any doubt that their games might not run, or have not been fully tested for modern system, GOG.com has introduced their Money Back Guarantee. This doesn’t mean that if you don’t like the game you get to return it. Rather, if in the first 30 days after your purchase the game will not properly run, continually crashes, or consistently hits a show-stopping bug, and their support team cannot fix the problem, then you get your money back. The guarantee covers all of their games, for buyers all across the globe.
The process seems fairly painless. Just log into your account, go to the support link at the top of the website, and you’ll see a list of the games in your library. To the right side of each game will be a link to “support articles” that go over the most common issues with fixes. If those don't work, hit the "Contact Us" button at the top right of your screen and reach out to them.
To help with questions on those extenuating circumstances, GOG.com has set up a FAQs section.
