[Update] Please add three more games to the "pay more than the average" tier (which is just $6.56 at the time of this writing): Legend of Grimrock, PixelJunk Eden, and the Complete Pack of Orcs Must Die! 2. For nine games, that's well worth the price. You have about six days before this Humble Bundle says sayonara.
[Original] Humble Bundle is at it again, this time with the Humble Jumbo Bundle 2 which includes seven games for those who pay at least $15 for the entire package.
For just a dollar donation, you'll receive Deadlight, The Incredible Adventures of Van Helsing, and Galactic CIvilizations II: Ultimate Edition for Steam, and for Van Helsing, that's the Complete Pack which includes Blue Blood, Thaumaturge, and Arcade Mechanic. But of course, that's just the beginning
Pay the average amount ($5.59 at the time of this writing) and you'll get Terraria, The King of Fighters XIII Steam Edition, and Crusader Kings II with the Russian, African, and Norse Unit Packs. If you more than $15, you'll get the cream of the crop, the Age of Empires Legacy Bundle that has Age of Empires II HD and Age of Empires III: Complete Collection. As usual, there are more titles yet to be unlocked, so it may be better to wait for a bit before getting in on the action.
