I only know it exists because it was mentioned in a YouTube video I watched ages ago now but this anime is very old (mid-late 80s). From what was explained to me from the video is that at least in Japan people would turn their D&D/tabletop campaigns into logs of player actions and events from the campaign. Eventually one of these went off to spawn an anime series.
Any help in locating this would be much appreciated! Everything I’ve been attempting hasn’t lead anywhere or people referring to isekai.
