After the recent GOG Black Friday deals which pretty much lasted all week, you'd have probably thought it would be some time before we'd see more awesome deals appearing on the site. As such it came as a big surprise to us to hear from GOG about their latest ' BIG Winter Sale ' which has begun today and ends on the 13th of December. In this mighty package you can grab over 500 daily deals for up to a massive 90% off over the course of the promotion. But that's not all, as there will be 18 bundles, a mystery game for 3 USD, and you can earn free games while shopping such as Divine Divinity for spending 5 USD or more and Blackguards Special Edition for spending 50 USD or more.
