Blood Bowl is a Fantasy Football game created by Jervis Johnson for the British games company Games Workshop (but now under the aegis of their Specialist Games division) as a parody of American Football. The game was first released in 1987 and has been re-released in new editions since. Blood Bowl is set in an alternate version of the Warhammer Fantasy setting, populated by traditional fantasy elements such as human warriors, goblins, dwarfs, elves, orcs and trolls. Blood Bowl has evolved through a series of rules revisions, boxed set releases, and electronic media.
