Neverwinter Nights was a full 3D engine but the gameplay and controls were clearly descended from Infinity Engine ,at least the first game... (I didn't play the second to be sure).
So it could do a 3D "Isometric", if you wanted to. As far as I know it is the only dedicated 3D RPG engine that wasn't intended to be controlled as third person "shooter" style controls.
