Awesome Games Done Quick is an organization that runs week-long, non-stop speedrun marathons for charity. This one benefits Doctors Without Borders, like the last three summer events. The last five Games Done Quick have raised a little under six million dollars, so this is a serious charity event.
The event starts this Sunday at 12:30pm EDT with a half-hour pre-show followed by an Any % run of Super Mario Sunshine for about an hour and a third, and that is followed by Zelda: A Link Between Worlds for about an hour and a half. Lots of PC games are included on their schedule too, including classics like Final Doom, Hexen, System Shock, and Serious Sam. It is scheduled to go, around the clock, until Saturday at just before midnight, plus or minus a few hours.
