The tabletop gaming-focused event will take place Nov. 17 - 19, 2017 at the Pennsylvania Convention Center in Philadelphia.
PAX Unplugged will be an exciting analog-focused extension of our already existing portfolio of PAX events. We've found that the Tabletop parts of PAX have grown and grown to the point where we said, "You know what? Let's make a show that's just that."
