If you want to help out some worthy charities while also buying PC games, today is the last day you will be able to so for two such efforts. Telltale Games' Great Adventure Game Bundle ends today with players able to download and purchase a number of adventure titles from Telltale and other game developers and publishers for $19.95. 25 percent of the proceeds from the sale will be used by a number of different charities.

Also, Stardock's Impulse PC game download site is holding the last day of its own charity efforts as a number of publishers have agreed to donate a portion of its sales from Impulse to the Child's Play children's charity.
