The original RPG replay trilogy was published in Comptiq magazine between 1986 and 1989 under the title *D&D Magazine Live Record of Lodoss War Replay* and is the basis for the main Record of Lodoss War novel series. Every arc primarily follows a new group. Parn's party, Orson´s party and lastly Spark´s party. Rules from Dungeons & Dragons, RuneQuest and Tunnels & Trolls were used due to predating Group SNE´s various RPG rulesets. The three RPG replays were adapted into three light novel format publications by Kadokawa Sneaker between 1989 and 1991 with some differences and a changed ruleset. A fourth RPG replay about Spark´s party was published in 1998 as a mini light novel. A fifth RPG replay, featuring a new cast, was published in 2020.
