GASPcon is an awesome convention that happens every year in Pittsburgh PA. I was fortunate enough to go a couple years ago and wish I could go this year. It's happening from Friday November 9th - Sunday November 11th at the Best Western in Greentree Pittsburgh.
Player and Event registration opens at noon on September 9th. There are 3 special gaming tracks this year. The Board Game Bonanza is a HUGE game library where players can check out a board game, gather a couple players and play it!! There are open gaming tables set up and you just play. Finished playing a game? Start another one! I had such a blast doing this and met a ton of awesome people.
The Indie RPG track is getting bigger and bigger every year. Not only are there going to be scheduled games but you can also check out some of the indie game systems from the library to try out. There is also the RPGA track complete with various heroic tier Living Forgotten Realms events. There are TONS of fun games so if you are looking for a convention to attend this fall in the Pittsburgh area this is the one to check out.
