I have a prototype of a card game I'm developing and I'm wondering if PAX Unplugged would be a good place to break it out to play it. I see they have open tables to play at, but I'm not sure of the rules regarding their use. Does anyone know if it's okay for me to set up a game on a table and pretty much play it for the duration of the show? I really am not a publisher so a booth makes virtually no sense. I'm assuming other prototype games show up there. If so, where? How?
