At its core, Secret of the Scarlet Hand is about completing an unpaid internship at a sketchy museum. Over the course of the game, Nancy solves multiple robberies, helps an amnesia patient regain their memory, and opens a monolith that hasn't been opened since the SEVENTH century for FREE. Not to mention she ends up almost suffocating to death next to a dead body in order to do it while the other suspects offer literally zero help. Instead, they chose to stand outside and wait for her with quippy one-liners in case she manages to escape certain death.
However, despite the insane ending, the majority of the game is just errands, phone contacts, and Nancy waiting around for packages like an Amazon Prime addict. Though I will admit this game has some of the best phone contacts of all time. You not only get the absolute icon that is Prudence Rutherford, but you can also call the Hardy Boys on their CAR phone! And then there's Poppy Dada who explains why she put a priceless family heirloom in her crappy painting, is weirdly obsessed with us seeing a dead body, and calls Nancy a prude! They're all a delight and they should be considering talking to them is basically half of the game.
The rest is just endless quizzes on Mayan artifacts which feel way more like being on Quizlet than actual puzzles. At least HER tried to spice up all this studying by adding a random amnesia plotline, which will feel totally relatable to you in a week when you've completely forgotten 99% of the Mayan history they tried to get you to learn in this game. Sorry!
