The old traditional ways of marketing are not dead. Gifts are a huge part of good marketing and so they are in the board game industry. Go to a game night and give the players free t-shirts and gifts. Whether it is for KS or for an already published game, players will love the gesture and word will spread.
Hero Time helps you get the game out there, and wishes you the best of success.
