Накилевий Тринадцатый, эсквайр
The original D&D was published as a box set in 1974 and featured only a handful of the elements for which the game is known today: just three character classes (fighting-man, magic-user, and cleric); four races (human, dwarf, elf, and hobbit); only a few monsters; only three alignments (lawful, neutral, and chaotic). The rules assumed that players owned and played the miniatures wargame Chainmail and used its measurement and combat systems. An optional combat system was included within the rules that later developed into the sole combat system of later versions of the game. In addition, the rules presumed ownership of Outdoor Survival, a board game by then-unaffiliated company Avalon Hill for outdoor exploration and adventure.

Налицо хитрый коммерческий план по впариванию кучи левых товаров.

Или ты про что такое бокс сет? Это набор книг + пара чарников или набор кубиков, популярный тогда формат продаж. Как пилили контент на DLC в старые-добрые времена, можно посмотреть здесь.

Сейчас подобные продукты называются starter set, но фишка в том. что тогда сетом продавали не только стартеры.
