From 1988 to 1992, SSI released a series of turn-based Dungeons & Dragons games generally referred to collectively as “Gold Box” because of the gold-colored boxes in which most of the games were sold. Most of the games have been made available again on GoG.
Gold Box Companion is a tool that adds features to the Gold Box games such as automapping, journal entries, and some interface fixes. It also includes some features that essentially mod the game, such as a character editor, a save game editor, the ability to teleport to specific map locations, etc.
In the early 1980s, TSR developed a syndicated radio show that would promote D&D by broadcasting audio examples of play. Jon Peterson of Playing at the World reviews some excerpts from the unreleased pilot.
