Trollcrusher was a seminal UK fanzine that began publication in 1977 and which focused mainly on D&D and AD&D.
It was edited initially by Bryan Ansell (later an owner of Games Workshop), then subsequently in order: David Row, John Baillie and Laurence Miller. Issues 23 to 29(the last) Edited by John Drake and Rory McLean although Laurence Miller still retained the rights to it.
Trollcrusher's format was to publish contributor material as a collection of 'minizines' (e.g. APA-like). Each contributor typed up and illustrated their own articles under a heading of their choosing. The material was not edited for content and contributors had wide latitude on the content of their 'minizines'.
Articles included scenarios, new character classes and monsters, adventure write-ups, reviews, general chat, and anything else the contributors fancied.
Notable contributors included Lew Pulsipher (designer of Britannia and Valley of the Four Winds), Brian Asbury, Paul Blackwell, Jeremy Goodwin, Michael Stoner (who went on to publish The Beholder fanzine), and Brian Dolton (who published Demonsblood).
Issues 1 - 6 were published in A4 format and subsequent issues were published in A5.
