Global Game Jam is a 48-hour, worldwide, video-game-making challenge, and Richmond developers aren’t going to be left out this weekend. Working alone or in teams, game developers will compete to see who can come up with the best corporate time killer at the end of two days. Locally, developers are taking part through 804 RVA, with artist-in-residence Zoe Quinn. The award-winning developer, artist and writer based in Boston has won acclaim for her interactive nonfiction game Depression Quest, which allowed gamers to see the world as someone living with depression. A full slate of free activities is planned for the weekend, starting with Quinn’s keynote address Friday, Jan. 24, at 6 p.m. For information or to register to compete, go to rvagamejams.com.
