After having a while to think about it, I feel like the closest comparison game to Nancy Drew: Mystery of the Seven Keys is definitely Nancy Drew: Ransom of the Seven Ships.
That is to say, both games were shit, had exuberantly hard puzzles for Junior/Amateur Detective mode, and had a painfully obvious villains, all while trying to desperately do fan service and cram in as many references to old games as possible.
The only difference between the two is that I would gladly replay RAN for the puzzles and the cozy "stuck on a private island resort in the" atmosphere. There's no way in hell I'm going to replay KEY anytime soon.
