I'll be at Origins in Columbus OH next week. I'm fairly easy to spot if you'd like to talk, at 6'6", 305 pounds (I was impressed with the size of NFL offensive tackles until I became that size), bald on top (not male pattern baldness, just a general lack of hair), mustache, glasses. I may be wearing a hat at times so the baldness may not be evident.
I am giving four different (free) talks about game design, Friday at 7 PM, Saturday at 11AM and 7, and Sunday at 10AM. One hour to talk, then up to an hour for questions. See the program for topic details.
