NGE stands for New Game Experience.
Its basically an overhaul of the game where almost 40 professions are reduced to 9, Jedi is now a entry level profession, and a new combat style( first person shooter style) replaces the old target and action, special action combat.
NGE took a really complex amd immersive game, a genuine virtual, world and dweebs it down to a barely enjoyable playing experience for those of us who knew and loved the old game.
Such is life....
