If you look at the current version of Dungeons and Dragons, you’ll notice that it’s labeled Fifth Edition. While it’s clear that the preceding edition was Fourth Edition and that the version before that was the Third Edition, figuring out the Second Edition is a bit tougher. OD&D is certainly D&D first edition, but there were two competing iterations of the game between OD&D and Third Edition. While AD&D 2nd Edition usually gets to credit as the bridge, one must not forget that there was another, very popular version of D&D out at the same time. This version, the Basic Set, did something new for D&D – it brought the game into the mainstream. D&D Editions: Dungeons & Dragons Basic Set (1977-1995) | LitRPG Reads
