The original Baldur's Gate 3, called "Baldur's Gate 3: The Black Hound" which got cancelled years ago, would have had absolutely nothing to do with the first two Baldur's Gate games either. On top of that, that game was going to be set far away from Baldur's Gate, in the Dalelands. At least this new Baldur's Gate 3 will be set in the city Baldur's Gate, unlike the original which would have been set in the lands Myth Drannor is located.
