At PAX Prime, Jon gave me one of each of three Card Hunter promo cards that had directions to the Indie Megabooth location of the game on the back and the website URL on the front. I had a few extras that I found lying around the Expo hall and gave them out to folks that I think might be interested in the game. I'm wondering now if Blue Manchu either have extras or would be willing to print up more of these cards closer to the game's release. I think taking them to Magic or D&D night at your Friendly Local Game Store or to other conventions or gatherings, or even sending them out in the mail to friends that you think might have an interest could help spread the word about this game. It is similar to the "retail box" idea that Time4Pizza and others brought up before is good as well, but just having a card with the Card Hunter URL and game info on it could be just as effective and take up less space. I agree with others that having access to the single player demo that was at PAX or a similar demo could also act as a gateway to spread the game to others. I know for one that those brief bits of exposure to the game at PAX have me and several friends experiencing mild withdrawl symptoms in anticipation of the game's release!
