Like the title says, this will happen this coming Wednesday (January 11th), courtesy once again of AGDQ (Awesome Games Done Quick), a speedrun charity event. This year they've gone back to playing to get donations for the Prevent Cancer Foundation, which works to stop cancer before it starts. They'll be speedrunning lots of other games too, like Super Mario Bros., Mega Man, Castlevania, and Katamari Damacy.
Please note the time is subject to change. Currently it's slated for 7:55 but earlier it was set for 8:14. The full schedule is here.
