[mooreds]

Have you shown the game to any players who don't know you? Local game store owners? Any bloggers who review games? Have you checked out the relevant reddits for the handles of people who would be able to give you intelligent feedback? Other forums (I don't know where board game players have out, but you should)?

Starting with your target market and getting them excited is how I'd start to market this.

Note that I have not done marketing of a physical product. I wouldn't take advice from me.

Maybe read a book about board game marketing?
