I guess this goes under Gamescom-news, as GOG.com is celebrating the convention by serving up some games at a 20% discount this weekend. The sale includes classic games that "enjoyed great success in Germany back in the good old days," including Jagged Alliance 1 and 2 and Master of Orion. But the biggest title is the modern The Witcher 2: Assassins of Kings which is available for $29.99 right now.
The sale ends on Monday morning.
