Nice to see The Networks by Gil Hova on this list.
I've been working on developing a couple board games for a couple of years now, and at the start of that campaign, I ran into Gil Hova's Bad Medicine on Kickstarter. On a whim, I sent him an email through his website asking for some advice about creating board games, not really expecting much of a response.
What I got was a 4-page email of well-thought-through answers to all of my questions, and a bunch of additional pointers furthermore. I met Gil at the Boston Festival of Indie Games in 2015. Super nice guy.
I have The Networks in my collection, but haven't got it to the table yet, but I eagerly await my first play-through.
