When people begin making a game, they usually hope for the game to find success among other people and become popular. Though there are designers who only design for friends and family or use game design as an outlet, I want to focus on the majority, who hope to someday sell their game and have it played by many. If you know anything about selling, you know that you need to have people talking. The best way to get people to know about your game is to build a community around it or introduce it to existing communities.
