10 Video Games That Were Secretly Judging You The Whole Time
1. Alex's Test - Prey
The 2017 horror game Prey features a very similar hidden morality system to Metro. Each action you take is taken into consideration at the end of the game, but it never lets you know that your character is being judged.
The moment of judgment happens in the secret post-credit ending. After your character, Morgan, survives the Typhon outbreak and decides the Moon Base's fate, they wake up in a lab where their brother, Alex, reveals the truth to them. It turns out Morgan wasn't actually the real Morgan, but one of the shapeshifting Typhons that Alex infused with their memories in order to teach it human emotions.
At that point, Alex begins to evaluate the results of his experiment. Depending on whether you acted with empathy or not - and how many of the alien upgrades and abilities you put experience points into - he will either consider the experiment a success and send you to Earth to act as an ambassador between humans and the Typhon, or conclude that you are a failure, destroying you and "starting over."
The first time you play Prey, this twist does a really good job of giving some weight to your actions. If you thought you could get away with ignoring survivors and killing with reckless abandon, you got what you deserved.
