Good luck on Event Reg day, everyone :D
We at Asmadi Games run an event room called the Department of Fun every year, it's in ICC 144 (across from the expo hall) and open from 10AM to 10PM during the show. We've got a full list of our events up at:
It has times, descriptions, and links to each event's page in the GenGon event system. Come play games with us!
Can you just drop in and play demo's or do you need a ticket to an event to go in the room and play?
