Summer Games Done Quick, the speedrunning marathon for Doctors Without Borders, is underway for the next week. As always there's a big variety of games being run, you can see what's coming up on the schedule.
I'm not super into speedrunning but I always make sure to watch these marathons a couple of times a year, it's about the right amount for me with a good amount of variety and a nice atmosphere around it, would recommend taking a look!
