YMMV / Siren 1

• Big-Lipped Alligator Moment: The original game's partial ending, which comes out of absolute nowhere and is guaranteed to confuse the absolute hell out of you. It's not the real ending, though.
• Fan Nickname: Suda Kyoya's abbreviated name and internet handle is SDK.
• It's Hard, So It Sucks!: The first game has been ported to PS4, and Trophy statistics suggest that many more modern players did not care for the difficulty. About 50% of players have the first trophy "Hit the police officer with the truck," (available in the first scene of the game), and after that only 2% of players got as far as "Unlock Stage Select."
• Nightmare Retardant: If you're unfamiliar with Japan's gun laws,^note Civilians do not have access to handguns, only shotguns and airguns with stiff restrictions (and rifles after they've owned shotguns for a couple of years); realistic-looking airsoft guns, as a result, are popular. Yoriko Anno asking "is that a real gun?" in response to Professor Takeuchi pulling a revolver from his bag can serve as this.
• Rescued from the Scrappy Heap: Yoriko Anno spends most of the early game whining about how miserable she is and bugging Professor Takeuchi or whomever else she gets partnered with. After she gets shot, however, and gets a blood transfusion from Kyoya Suda, she apparently gets a dose of his nascent badass-itude.
• Signature Scene: The scene where Tomoko runs to find her parents while the Shibito stop attacking her for some reason only for their POV to reveal that she's been turned into a Shibito herself. The followup level, where Harumi must escape from Tomoko and her now fully Shibitofied family while completely unarmed is considered the game's signature level.
• That One Level: Reiko escorting Harumi through the school in the first game, mainly thanks to a game 'feature' where collected items aren't kept if you die and continue, even if you hit a checkpoint after collecting those items. Here, it's required that you use Harumi to grab an item just before the halfway checkpoint in order to proceed with the game, and so any deaths in the level will require you to start from the very beginning, lest you miss the item. Did I mention Harumi literally can't get anywhere near a Shibito without dying, or that her AI routine for this level (seek a hiding place whenever you get caught) sometimes causes her to run between you and an attacking enemy?
• The Woobie: Harumi Tomoda and her teacher Mrs. Takato had very sad lives even before the game begins. Harumi is an innocent little girl who already lost her parents in a car accident (the car was struck by lightning) before being trapped in the village. Reiko Takato lost her own daughter a few years earlier, when a large wave struck the beach they were on. Separated by the wave, she managed to swim two other children to safety but couldn't find her daughter in time. The only reason the two of them were even at the school the night of the incident is because Mrs. Takato and kindly principal Mr. Nagoshi tried to start a stargazing club for Harumi, but nobody else joined. Mr. Nagoshi is turned into a Shibito early on, and Harumi and Reiko spend much of the game running from him — before a desperate Mrs. Takato finally lights a truck on fire in a Heroic Sacrifice, buying Harumi time to escape. Even as a Shibito, Reiko's final act is to tackle Mr. Nagoshi into a hole, giving Harumi the time she needed to escape Hanuda once and for all. Harumi ends up being the only survivor of the Hanuda incident in the present, wandering out of the ruins — though if Professor Tamon's long-lasting trauma after being found in almost the same circumstances thirty years ago is meant to serve as any indication, Harumi may not have the brightest future ahead of her.
