Today marks the beginning of Good Old Games' holiday sales. They're offering most of their catalog at a discount until January 4th.

Every game in their library aside from December releases was marked down so there's 171 discounts live now. Some of the discounted games include Fallout, Duke Nukem 3D, and Earthworm Jim. To help you sift through their virtual bargain bin, GOG has a sortable games list on their site that breaks the titles down by genre.

Good Old Games is also offering free copies of Tex Murphy 1 + 2 to all comers. That particular giveaway ends on December 24th.
