Game-related charity Gaming For Good is offering consumers a chance to buy games in exchange for a charitable donation to Save the Children. The catalog is pretty extensive, offering titles directly from the folks that make them and through digital distribution services such as Desura and Steam.
At a glance, the catalog includes Infinite Crisis Priority Access, Awesomenauts, the Magicka Collection, War of the Roses: Kingmaker, Trine, Trine 2: Complete Story, Toki Tori, Limbo, Alan Wake's American Nightmare, and many, many other titles. Games are purchased by getting points from making donations.
Gaming for Good is the brainchild of AtheneLive, a gaming community launched by the popular Twitch streamer Athene (Bachir Boumaaza).
