When it comes to nerd hobbies, the convention scene is bifurcated. There are local, volunteer-driven cons that put a lot of effort into building content from enthusiasts around the area. There are also the massive, national affairs that bring attention and revenue to their parents. Gaming cons moved quickly into the latter category, even if the initial efforts were modest; both GenCon and Origins came to prominence after their alignment with TSR and GAMA, respectively. And now there’s a massive leader in the corporate con sphere: Penny Arcade Expo, or PAX.
