Its my 2nd year for my event and im worried its going under the radar. Similar events to mine that are improv related seem to be doing much better. Meanwhile im at 4 tickets, :( Any ideas on how to drive the numbers up? From what I gathered, last year it went well and was well received, just low numbers.

Post it in the Event forum here, and in the Friends of Gen Con FB group.

I recommend expanding the scope of your notifications.

These forums are a good place to start, but they only reach a small fraction of the people attending Gen Con.

Try game forums like boardgamegeek, RPG forums like enworld and rpgnet, and if you're really brave, dip your toes into reddit.
