The original
Dungeons & Dragons Basic Set was published by
TSR, Inc. in 1977. TSR hired outside writer
John Eric Holmes to produce the
Basic Set as an introductory version of the
D&D game. It incorporates game concepts from the
original 1974 D&D boxed set plus
Supplement I: Greyhawk. which was released beginning later that year. Holmes preferred a lighter tone with more room for personal improvisation, while Gary Gygax, who wrote the
Advanced books, wanted an expansive game with rulings on any conceivable situation which might come up during play, and so could be used to arbitrate disputes at tournaments. The boxed set included a set of polyhedral dice and supplemental materials. For a period in 1979, TSR experienced a dice shortage. Basic sets published during this time frame came with two sheets of numbered cutout cardstock chits that functioned in lieu of dice, along with a coupon for ordering dice from TSR. The rulebook also included a brief sample dungeon with a full-page map. Starting with the fourth printing in 1978, the two booklets of maps, encounter tables, and treasure lists were replaced with the
module B1
In Search of the Unknown; printings six through eleven (1979–1982) featured the module B2
The Keep on the Borderlands instead. Peterson wrote "as Arneson's lawsuit loomed, TSR made a very pointed substitution to the contents of the
Basic Set: they rotated out the
Dungeon Geomorphs and
Monster & Treasure Assortment booklets, replacing them with Mike Carr's
In Search of the Unknown module. [...] It was a good idea to target a module at beginning dungeon masters — but it also had clear implications for the legal situation. Previously, when Arneson sought a 5% royalty on the whole contents of the
Basic Set, he was effectively asking for money that was going into Gygax's pocket. Now, he would instead be asking for money earmarked for his friend Mike Carr". Carr received royalties for
In Search of the Unknown when the module was sold alone and when it was included in the
Basic Set. After the September 1979 disappearance of
James Dallas Egbert III,
Dungeons & Dragons received "mainstream notoriety. And with that, sales of the
Basic Set rose dramatically. Right before the steam tunnel incident, the
Basic Set might have sold 5,000 copies a month. By the end of 1979, it was trading over 30,000 copies per month, and only going up from there". Following Carr's financial success due to his module being included in the boxed set, Gygax changed the module included with the
Basic Set to
Keep on the Borderlands which was a module he wrote. ==1981 revision==
