The gaming arm of the SXSW fest takes over the Palmer Events Center. Nintendo, Marvel, NASA, and lots of other folks will be supplying the fun and, of course, games. The adults might want to check out some of the panels, but the kids will likely stick to the pro-gaming tournaments and other flashy bits. It's free, there's parking, it's everything SXSW can be without all the hassle. Fri.-Sun., March 8-10. Free.
