Periodical with numerous articles written in support of the Runequest RPG, and more specifically, the campaign world of Glorantha. Last issue was #20, released in 2002.
The TRM magazine had a primitive beginning, much like a fanzine. Indeed, issue 1 billed itself as a fanzine, though this changed on the cover of issue 2. Issues 1-6 were hand-stapled photocopied sheets. I have also seen issues 7 and 8 fanzine-style, as well as the more professional saddle-stapled style seen in later issues.
