In some of the earliest games produced by Tactical Studies Rules, we see a mysterious credit to an entity called "WAW Productions." WAW gets a prominent nod on the cover of the TSR hit location rules Bio One (1976). More striking is the 1975 notice on the title page of Empire of the Petal Throne that it is "Presented in Association with Mr. William J. Hoyt, W.A.W. Productions." That hints at a long forgotten fact: before TSR licensed Petal Throne, WAW had already secured an option to publish it. To learn the origins of some of TSR's seminal titles, we must therefore study the history of the obscure Twin Citites imprint known as World At War.
