Telltale Games has teamed up with several developers to sell six great PC adventure game games in one package. "The Great Adventure 2010 Bundle" is priced at $19.95, with 25 percent of the proceeds going to five different charities: Child's Play, EFF, The Leukemia and Lymphoma Society, Nyota e.V., and the World Wildlife Fund.

Included in the bundle are Daedalic Entertainment's The Whispered World, Deck13 Interactive's Jack Keane, the King's Quest Collection (with seven games from the series), Hothead Games' Penny Arcade Adventures: On the Rain-Slick Precipice of Darkness, and Telltale's Puzzle Agent and Sam & Max Season 2.

The last two of those titles are unlocked after the sale has reached certain milestones (5,000 sales for Puzzle Agent, and an unspecified amount for Sam & Max). So far, Telltale has sold nearly a thousand of these bundles -- the sale ends on September 9th.
