Everything. The rules, the figures, the town, all grew out of an incident at a convention. A guy had a huge Old West set up. I got there too late to play, but watched on and off instead. I asked the guy running it if I could look at the rules sheet, just to better understand what was going on. He sneered at me, and said "If you wanted to know how to play, you should have got here earlier."
Eff you buddy. I walked over to vendor selling Dixon Cowboys (at the time, the only manufacturer available. They survive now as the Dixon Gang). I went home and started writing rules and making a town.
