Good Old Games is having the rather large Atari Collection on sale for 50% off this weekend. Some of the games have been on sale a couple of times before, so here's your chance to grab them if you had missed out. Notable games that can be picked up for cheap are Alone in the Dark 1+2+3 for $2.99, both Independence War games for $2.99 each, The Witcher: Enhanced Edition for $4.99, Master of Orion 1+2 for $2.99, the Star Control games, and the Total Annihilation games.
The first two Rollercoaster Tycoon games are on sale as well, as are the Blood games and Outcast. Can you still count the voxels? Remember how people once thought those would become the norm instead of polygons? Oh, how we laughed at them! Finally, Chris Sawyer's Locomotion is $2.99. It's a bit like OpenTTD, but less "open" and with some fancier tracks. A great way to lose hours of your weekend.
All these games and more are half price, regardless of how many you buy. If you unselect them all, you get to see the original prices in case you are terrible at math. Go forth and buy those games that you won't play within the next 6 months!
