What, you thought Steam was the only digital game vendor that could have a summer sale? Well CD Projekt wants to tell you that you're wrong! Classic games, modern games, they're all on sale!
Obviously GOG's main claim to fame is its extremely extensive vintage games library, stretching back through the early 2000s and into the 1980s. However, GOG also has a couple of modern games on sale, including CD Projekt's own acclaimed Witcher series. And of course, all of it is DRM free (not that DRM bothers me as much as it does many).
Browsing through the site I think I might pick up Alpha Centauri. Sid Meier's new game Beyond Earth has raised my curiosity about the old sci-fi title, which I never played back in the day.
