I noticed that you mentioned that you are not a sales man and described a person you knew that was great a creating hype about a  produce which may go against your personality. But I would say that to get best results from other people's stories about any Kickstarter like service, is to to have a prototype ready to go. It shows that you have something besides an idea and some direction which is why you need the money to bring it into production. I don't like selling either but if you believe in the game idea, had a prototype (rules, card layouts, etc.), then the IDEA will sell itself. People will see value in the what you are trying to achieve thus you are not selling anything but creating something people WANT to bring to fruition because it intrigues them as much as you. 

I just wanted bring another perspective. 
"Ideas sell themselves because people see value in it."
