they were skilled enough to give ambiguity
play the first game carefully again there are hints the surgery may have worked or would have not worked killing Ellie for no reason
a lot of failed experiments potentially with a of children
that's what I loved about the last game
the moral ambiguity
it's perfectly fine to say fukk Joel though in the sense we never got to know
I agree bro I picked up on the ambiguity that’s why I love the story in both games. I beat the first game like 6 times. I’m not saying what I believe is how it is end of story
