Just got my DW corebook in the mail today, have to say after the snooze fest that 4e was to read, it's great to actually open up an rpg that actually makes me what to devote the time to reading it that is necessary to play the game. So far I'm liking what I've read and if anything would compare it's tone and flavor as very Warhammer-esque. In fact I would say this book could easily be to Warhammer FRPG what D&D was to AD&D....I'll post more after I digest it.
Dragon Warriors and Warhammer are quite incestuous. Oliver Johnson and Dave Morris have worked for Ian Livingstone and Steve Jackson on a number of occasions, (White Dwarf, Warlock Magazine, Fighting Fantasy Gamebooks et.al). I remember reading somewhere that some of their ideas segued into Warhammer; I recall reading somewhere that they were working on 'Tetsubo' the 'Oriental Adventures' of Warhammer Fantasy Battle at one stage. Of course, I cannot find my source now. Warhammer Fantasy Battle started around 1983, Dragon Warriors was first published by Corgi Books in 1985, I think. Morris has also worked with Jamie Thompson, who is another guy to work with Games Workshop. If you can, have a look at Fabled Lands, Way of the Tiger and Bloodsword Gamebooks. Quality stuff. Also Talisman of Death. My all-time favourite.
