So, one of my friends from High School and I designed a board game. Well, we've designed a couple, but SIEGE! is the one we actually still enjoy playing (not everything can be a winner). Its extremely important to be completely honest with yourself as a designer, but don't let a few hiccups halt a game you love. Anyways, after playing with our friends and getting a lot of positive feedback, we decided to pursue this dream of becoming a published game designer.
The first thing I did was research, and research, and a little more research. My conclusion: publishing a game is hard. While doing all this research, I realized that I was spending all this time worrying about things that are so far in the future that I wasn't actually making any progress. Yes, knowing what you're about to get into is important, but so is the sense of accomplishment.
Learn as you go. Look at the next few steps, one month at a time, and learn how to do those as best as you can. One of the best resources I've found is Stonemaier Games. Jamey is absolutely fantastic. If you decide to use kickstarter, I've added a link to Stonemaier's Kickstarter Lessons, of which there are well over 100.
I'll definitely highlight specific articles that were a huge help to me as I go.
The first step of publishing a game is to decide to take the first step.
Happy Gaming!
