I rarely straight-up promote publications here, but I really do think you should go check out Zolani Stewart and Alex Pieschel’s The Arcade Review, a monthly(?) publication of criticism about experimental and avant garde games.
It is $5, and that $5 is well-spent. So far, the pieces I have read are really interesting and comprehensively excellent. I will post up an actual review at some point, but for now, go check it out.
