Sorry, but I think that Dark Forces also has its own engine. It looks like Doom, true, but it's not. It's got real 3d -- rooms above rooms, etc -- things the doom engine quite simply cannot do. And it's not the Quake engine because it was out before Quake and has sprite-based characters. So no, the Lucasarts FPSes have their own engines. Only the Raven ones use ID engines.
