The guys at On Board Games have a long history with game and fandom events. We have worked on local and regional gaming events that drew between 15 and 1500 attendees; and all regular contributors have worked with major game industry companies at some of the largest game shows in the industry. Between them they have attended more than 200 game events and they think they have something to say about the phenomena.
In addition to being great tutorials on how to prepare for events and providing an overview for the kinds of events that can be found in the wilds of gaming some of these episodes include segments that might be of use to attendees or game company reps preparing for convention season. Also, there are some episodes where we've discussed game events we've attended.
