Paul Sottosanti – Paul Sottosanti is my friend and a brilliant card/board/video game designer. My favorite article is his Tiny Adventures teardown, which has a lot of good talk about social gaming especially.
Sirlin – Sirlin is another board, card, and video game designer. Sirlin’s articles are super crunchy. My favorite article from this blog is Playing to Win in Badminton, a response to the 2012 Olympic Badminton debacle.
I’m always on the lookout for more, comment if you’ve got em.
