An anonymous reader writes: Following on the fortieth anniversary of Dungeons & Dragons last year, another formative influence on modern gaming is celebrating its fortieth birthday: Games Workshop. Playing at the World covers the story of how the founders, Ian Livingstone and Steve Jackson (not the other Steve Jackson), started out as subscribers to the 1960s British gaming zine Albion playing Diplomacy by mail and (in Ian's case) publishing silly cartoons. When Albion folded at the beginning of 1975, Livingstone and Jackson formed Games Workshop with its own zine Owl & Weasel as a way to bring "progressive games" (as in "progressive rock") to the UK. Shortly thereafter, when they discovered Dungeons & Dragons, fantasy and role-playing games became their focus. After Owl & Weasel grew up into White Dwarf in 1977, its famous "Fiend Factory" column ended up populating the D&D Fiend Folio . And in the 1980s, of course, they brought us Warhammer and their retail stories brought stylish miniatures to many a needful gamer. Happy birthday to Games Workshop!
