Artifact, lightning on walls, Indy, interior reveal, mummies, bugs, bridge, snakes, behind giant face. Other than that I can’t make out what’s in dark before the darts(?) and boulder (also shared). That’s a lot less tan 80%
Well if you want to break it down...
The entire queue as there is no train tracks to go under
First scene not based on three doors and choices and the whole room is different
Assent hill room with all new scenery and a crystal skull idol (No Mara)
First door scene with Indy is new lighting and effects and scenery
Entrance to Skull room makes it look like your going down temple stairs not just a track
All new scenery in Skull room and effect/lighting
Skull is different
Over the bridge in center room is a smoke tornado
Snake room the scenery is different
Snake is different
Inside skull is new scenery, lighting and idol
Temple god that blows smoke ring at you as you ride through it
Blow dart room complete different
So is it the same ride, for sure it has a good majority of similarities. Is it different than Disneyland's? Yes about 80 percent of everything has changed in some way or another. I'm speaking of details and the look. OLC would not allow a carbon copy exactly.
