You pledge the amount you want, but nothing gets charged until after the project funds. And only if the project funds. You are out zero dollars until after the project funds. By pledging $30 or more, you are securing your entrance to the convention.
We pride ourselves on having a wide variety of types of game events. There will be card games, board games, RPG events, and miniature war game events. We have 20-30 volunteer GMs running events, but feel free to bring your favorite game for a pickup event!
Unfortunately no there won't. The base goal money goes to pay for the venue, badge supplies, printing the program book, promotional flyers, concessions, kickstarter rewards, etc. For MaricopaCon to be sustainable it cannot run at a loss. It hasn't so far. But if the project doesn't reach $5500 there will not be a MaricopaCon 2016.
