While this is only tangentially connected to rpgs (there are some video games games based on rpgs), this is about a friend of mine who is part of a charity drive that will be video playing games for 24 hours straight. Basically its like sponsoring someone for a marathon, only he'll be playing games instead of running. A person donates a certain amount of money and they can watch him as he plays. At the end he is even giving a free Steam game as a raffle prize to those who donated.
His chosen charity is Boston Children's Hospital. He will be doing this starting on the 20th, so if you want to help out you'll have to do so now. For more information, you can check it out here.
