I I.J&E.T. he discovers the tomb of the first emperor and find the heart of the dragon in his mouth, but in Indiana Jones and the secret of the Sphinx, he also discovers the tomb and the emperor's tomb, he even rides the skeleton out and losses the head down the mountain side, know that does not make sense at all. The weird thing is if the manual creator Gregory Harsh(?spelling), did extensive reasearch as he clamed in the interview, you think he would have found that out, same with the people at lucas arts.
