This specifically is worse than Mark's challenge with the two girls, in my opinion. Far worse.
Why give Anna several totally different options in that flashback to then make them absolutely meaningless? The only outcome is revolting for many of us players. It's probably the most absurd thing of the game.
And I know that this has been mentioned a couple of times before, but I remember that the voice said at the very beginning of the story that the collars hide needles with deadly poison. Later John's collar cuts his head off
. I don't know if this was ever corrected in the early explanation and I'm definitely not gonna "replay" (or rather rewatch) this from the beginning to check.
Btw, Boxed In is a fuckfest with mediocre renders. White Cube has very decent renders and had a much more promising story until the two big fuckups happened. Credit where credit's due.
