What is a specific part of a video game that made you quit playing that game?

Spec ops the line. White phosphorus.

Can I ask why? That’s where I gave up, but I keep having trouble articulating why.

You’re forced to do something stupid and evil for the story to progress. Even if you try to avoid it, the game won’t let you continue unless you commit an obvious war crime.

Ah yeah, I think that’s it. I was felt mad that I kept trying everything to avoid dropping phosphorous. They take away your agency, and force you to do a war crime. I’m guessing that later they call you out for being a bad person for doing that?
