Good Old Games has quite the selection of classic game titles, plus it will start to offer some newer ones as well. This is the holiday season though, and that means it is time for some holiday sales. GOG.com's holiday sale is nearly here, and to kick things off, it will be offering The Witcher 2: Assassin of Kings at 40% off. GOG will also throw in a copy of The Witcher: Enhanced Edition at no extra cost, so this is a good time to try out one of the best RPG series around. That sale will only last for 48 hours starting on Thursday, December 8th, but then on Saturday the 10th, GOG.com will be offering game codes for a variety of games. Masters of Orion I + II and Realms of Arkania I + II are the main ones, plus there will be codes for other games up for grabs. All you need to do to get a code is follow GOG.com on Facebook or Twitter, or be signed up at the site's forums. Monday, December 12th, will have Empire Earth: Gold Edition be given away for free to anyone who adds it to their cart until Wednesday, December 14th. Monday will also have nearly every game on GOG.com drop in price by 50% until January 2nd, 2012. All in all, this sounds like a great way to pick up some classic games for a cheap price this holiday season.
