Games Done Quick (GDQ) is a series of charity video game marathons where players complete games as quickly as possible. These events feature a wide variety of games, from classic titles to modern releases, and are streamed live online. The marathons typically last for several days and raise money for various charities, such as Doctors Without Borders and Prevent Cancer Foundation. Participants often showcase their skills and strategies, while viewers can donate to support the cause and interact with the stream through chat.
