Agree with Taxman here... this game never really had a fighting chance.
As a owner for a couple years now here is some of my opinions:
Of course, the proverbial incomplete code. Advance scene on skill shot does nothing. Although I don't care about Crystal Skull (still the worst of the franchise by far) the lack of cut scenes in the latter half of the movie - even the big *aliens* reveal. Unbalance scoring on map room.
I still think they should've incorporated one more ramp in the game. Make the Ark smaller, have the Temple of Doom shot be a mine cart ramp (missed the ball there) and have the trap ball scoop be the Last Crusade shot. Fix the redundant "hurry up" orbit shots. Play a different Indy theme while in a certain movie mode.
It's apparent Stern didn't really care about this title after the movie starting getting bad reviews, so they never saw fit to address some of these issues.
