order of the griffon to me is the best US only release. I wish you could roll your own party, but other than that minor setback, its a perfect AD&D game, worthy of GoldBox status.
Its also the best non computer release of an AD&D game. It holds true to the original games better than the rest do.
Pool of Derpiance on NES was janky, Eye of the Beholder for SNES had annoying frigging music, and Warriors of the Eternal Sun just wasn't the same!
