Jo from GamersFTW writes: "Well, I didn’t see that coming! A phrase which many of us will have uttered. Plot twists are something that were once reserved for films and television shows, but as games become more immersive it is no surprise that the narratives and plot take on a film like quality. Be it a betrayal by someone you trusted, an unexpected death, or something which you just simply couldn’t imagine being true until it was spelt out for you."
A fair list, but there are some MASSIVE examples that didn't make this list.
SPOILER WARNING
Primary example - because it's so well known - is Bioshock 1's ending, but my personal title I'm surprised didn't make this list is Spec Ops: The Line. It was quite a morally hard-hitting twist that game had! Should play it twice over to really see the full picture of the twists (what's real, and what's not)!
EDIT: That RDR one though.. Oh my. Those feels! D:
Yea, wow, the big revelation in Star Wars: Knights of the Old Republic was enough to make a great game into a legendary one. That game had a better written plot than most of the movies.
