These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Darkness-Induced Audience Apathy: Both games involve a large cast of characters, all of which are nasty egotistical stereotypes. The main goal is to spy on all of them to learn their little secrets, such as who is blackmailing who and who has had an affair and such. And then they all die like mayflies, slaughtered one by one by a serial killer, which you cannot prevent. So why exactly should you care about any of these characters?
Fridge Logic: In the first game, there's several ways for Laura to get murdered by an unseen figure, even very very early in the game. But once you've beaten the game, it's obvious that nobody had any motive to kill her, especially not the murderer, and certainly not that early in the night. She was actually the one person present who the murderer didn't want to kill.
Fridge Horror: If you take a look at the instances in which Laura can be killed by the mysterious figure, taking a shower, hiding in the attic, and hiding in the closet, Laura is simply grabbed and killed without the murderer even looking. too late to see it was her best friend.
This is potentially a case of Gameplay and Story Segregation, as The one suspect in the mansion who likes Laura and doesn't want her to die being the murderer and never killing her would actually give the true culprit away too easily. Although near the end of the game, Lillian is so unhinged that she argues with Laura and thinks she's "as bad as everyone else" if you talk to her while she's writing in her diary.
