Pfft! Shameless knockoff, indeed!
Not to mention it was also the first to allow overlapping levels so that you could have multi-story buildings and even real bridges. Or that it actually had a story with fully voiced cutscenes.
I also recall reading a long time ago someone discussing the inner workings of the Jedi engine. About how the devs actually used window portals looking into other parts of the map to make various sections feel larger. Which was something completely unheard of at the time.
