AD&D 2E isn't good because it existed solely to deprive Gygax of his royalties.
Gary Gygax himself in 1985 had begun consideration of how to develop a 2nd edition of Advanced Dungeons & Dragons from the existing AD&D rulebooks and of the various alterations desired in terms of corrections, new rules, additional information, and redesign. In fact, Gygax actually wrote an article for Dragon Magazine on this very subject, titled "The future of the game: What the Second Edition books will be like", which ironically appeared in issue #103 (November 1985), the month after he had been ousted from TSR. As with the original AD&D rulebooks, Gygax would have published the 2nd edition books one at a time, starting with a Monster Manual that would combine material from the original, the Fiend Folio, the Monster Manual II, and other TSR publications, followed by a Players Handbook that would add portions from Unearthed Arcana and Oriental Adventures (plus completely new material, such as mystic, savant, and jester subclasses), and completed with a Dungeon Masters Guide. If anything, the change in TSR's leadership actually delayed initiation of the 2nd edition's development, so that the three AD&D 2nd edition core rulebooks did not appear until mid-1989 (nearly simultaneously).
