What is the difference between Lego Indiana Jones Original and Complete Saga?

The Complete Saga does cover the first three movies like the original game, but the levels are completely new. It is not just a rehash of the same levels, although the storyline is the same.

"The Complete Saga" includes 6 worlds, each of which contains 15 playable levels plus a few extra activities in the "hub" world and an extra bonus level. The first 3 worlds follow the storyline of the 3 older movies (1 world for each movie), while The Crystal Skull is covered in more detail in the last 3 worlds.

So you are not just getting a few bonus Crystal Skull levels for the "extra $30", you are getting a complete new game. So if you like the Lego games, you could buy both and not have any duplication in gameplay (although you may get a sense of deja vu since the storylines overlap).

Lego Indiana Jones 1

this is what i think (sorry if its wrong i am only trying to help you out)

the original indy is all the movies except the last 1 the crystal skull.

and the other 1 is all the movies

so i would get the cheaper 1 because the difference is that it doesn't have the end movie

Well the Lego Indiana Jones Orignal contains the all the old movies excluding crystal skull. Its just like Lego Star Wars 1 only indiana jones. Complete Saga on the other hand allows you to build your own levels characters and includes crystal skull. Plus its also a newer game than orignal lego indiana jones. Hope it helps
