I think they're pretty different but perhaps that's because Indy is better themed with a better known story to it therefore I'm concentrating on the story more. Dinosaur seems to race from one stop to the next; Indy has some of that too but there seems to be more purpose to it because of what's going on in the story. In Dinosaur I felt it was just racing to the next dinosaur. Much more stop and go. Indy will slow up, back up and/or speed through depending on what's happening in the story at that point.
Terk-1: there is one drop but it's a short one.
