Cards Against Humanity, the mildly evil card game, had a Christmas sale, where they released a season-themed booster pack at $pay-what-you-want. After the sales all came through, and they paid for production and expenses, they donated all the profits -- all of them -- to the Wikimedia Foundation, best known for being Wikipedia.
"From the outset we decided we wanted to give all the proceeds to charity and that made it more fun for us," said [co-creator Max] Temkin. "We weren't really worried about the bottom line, we were really able to do it as an experiment and do it in a great way."
After covering an assortment of costs including manufacturing, shipping and development they were left with $70,066.27 in profit, of which every cent was paid to the Wikimedia Foundation.
"We wanted to pick something we thought the users of our game of had heard of and believed in and used and we felt like Wikipedia is pretty unique in terms of having universal appeal," said Temkin. "It's something that helps a lot of people of all different classes and levels of education in different places all around the world … We also support the social mission of Wikipedia."

I still haven't gotten the chance to play Cards Against Humanity, and I'm still not totally sure I like its hipster-awful ethos, but I absolutely approve of this decision.
