I got my copy through the post after backing it on Zine Quest. Really, really beautiful object, itself worthy of the epithet 'Kozmik'! The square(ish) format and bold colours reminded me of early 90s SNES game manuals (that's Nintendo famicom my American friends).
The content would fit any Space Opera or Sword & Planet game (especially as there is a literal Sword Planet!) campaign: Troika, Hypertellurians and Solarblades & Cosmic Spells all spring to mind, but if you don't have any of those there are a bazillion hacks of the Nate's own Tunnel Goons system that would fit.
An absolute triumph: my one objection would be that the beautiful print edition is just too tempting for my toddler, who smears their grubby fingertips over it at evey opportunity!
