It was around this time last year when the Steam Potato Sack sale appeared, which offered 13 indie games at one low price. That bundle tied into Valve's impending release of Portal 2 since potatoes play a role in it (if you have yet to play the game, do so now). Today Valve is offering the Potato Sack Reunion, which once again offers 13 indie games at one low price. All you need to do is part with $20 and games like Amnesia: The Dark Descent, Super Meat Boy, Toki Tori, The Wonderful End of the World, Killing Floor, and Defense Grid: The Awakening will be yours. If you already own some of these games and purchase the bundle, then you will receive extra copies to give out. This sale is a midweek deal so it will expire tomorrow at 4pm Pacific, so you need to act fast if you want to play any of these great indie games. This Potato Sack sale may become a yearly thing unless Valve has some unannounced project utilizing potatoes releasing soon.
