I'm glad I'm not alone. As I was looking at the adventures and how they were presented, it became very clear that there is a definite escalation that progresses through them. Given that the first one puts the runners into the middle of a fight between shedim and bug spirits, and River City Shootout was written specifically as a Prime Runner level run in a PR-level setting, that shouldn't come as much surprise that it gets harder and crazier from there. And then, you know, Praxis.
