Lego Indiana Jones 2?

would love to see it, but I don't see how they can stretch the Crystal Skull storyline into a game of that size. My suggestion, dedicate a section to Crystal Skull, and then sections for the original Indy games turned into lego format, i.e. Fate of Atlantis, Infernal Machine, Emperor's tomb.
my 2 cents
