Good Old Games, or GOG.com, has put together a their 2012 End of the World DRM-Free sale, which runs from now until tomorrow, when the world is expected to end.
Everything must go. As such, every game is being sold at an enormous discount, with some titles being discounted to up to 80%. All of the games being sold run on Windows, with some of them also offering Mac OSX support.
The games are being sold at higher discount within various packs, like the Daedalic Adventures pack, which contains every adventure game from the series; the Santa in Space pack, which includes space-themed games; or the Cyberpunk & Steampunk Bundle, which includes all the titles from Deus Ex, Thief and Anachronox.
