Matthijs Holter's (b. 1972) first game, BeastWorld, was written during English class in 1987. Three xerox copies were sold to friends. It was, of course, awesome.
In 1993, he started the fanzine Imagonem. In 2004, his game Draug was published by Spartacus. In 2008 he co-edited Norwegian Style, an anthology of Norwegian RPGs. He also designed Fuck Youth and Zombie Porn.
