Deponia 1,2 and 3 on sale. I fell in love with the first game ever since I bought the Daedelic Entertainment bundle at a humble bundle deal. If you are a fan of point and click adventure games such as Monkey Island, King's Quest, Simon the Sorcerer and the like, you will definitely enjoy this game.
Good deal, but it isn't 85% off RRP - it is $39.99 US at Steam for the complete edition which has all 3 plus some extras.
