When the game lets you make an extremely dumb decision that kills you/gets you a game over/makes it impossible to win

Basically what it says. The extremely dumb decision that can only end in your death, game over, or make winning impossible is a valid option you can choose.

Mass Effect 2. Morinth is an Ardat-Yakshi, an Asari with a genetic condition that causes the Asari mind meld to burn out her partner’s nervous system and give her a euphoric feeling. If you choose her over her mother, Samara, she says that Shepard is special and can survive where everyone else has died. She’s lying and you die like everyone else if you sleep with her.

Nier: Automata. There are a lot of unique game overs in the game that usually involve dying during certain events. A few involve making truly idiotic decisions. Engaging your self destruct inside the pressurized space station blows it up. You can remove a component that is essentially your brain and instantly die. You can eat a fish that is said to be extremely delicious but destroys the insides of androids.

Lords of Aswick. One possible scenario in this choose your own adventure game is that you take in one of the king’s bastards as your squire. The king just had a legitimate heir and started killing his bastards to secure his heir’s claim. Later on, you have the option to declare in open court that your squire is the king’s bastard. The next scene is your execution with bastard having just been executed before you.

But that's what we do in video games all the time (press random unlabeled buttons, I mean)! That's how DOOM works! Also, you would think the planet-destroying laser would have some precautions against activating it by mistake.

It’s been a long time, but as far as I remember, there usually ARE more checks in place, including an engineer who’s supposed to be supervising that station at all times, but the ship has a liiiittle rogue AI problem at the time.

Exactly, I thought I’d unlock a weapon, turns out unfortunately I was very right

Yep, that's what I did in my first inept playthrough. It was the perfect ending honestly. There was a step I had forgotten about that makes it not a Bad End.

At least the evil computer threw me a party.
