Basic D&D Compatible Product

A collection that groups role-playing supplements and adventures compatible with the Basic Dungeons & Dragons rules but not produced by the original publisher. It includes unofficial products from the late 1970s and early 1980s as well as modern material designed for use with the Basic edition ruleset. Items in this category are third-party or unbranded retroclone-compatible works; materials explicitly labeled for other retroclones or produced by the original publisher are excluded. The focus is on usability with the Basic D&D rules rather than official licensing.
