Spoiler them please for people who don't know. I feel like all 5 of these are the worst of the worst.
Star Ocean III Til the End of Time
Mass Effect 3
Zero Time Dilemma
The antagonist is a blind, deaf, and dumb man in a wheel chair who the game barely acknowledges is there until the reveal. There is some very minor foreshadowing but it's purposely designed so you'd overlook it. He then gets up and reveals he's not blind, deaf, or dumb and he was there the whole time.
Heavy Rain
Final Fantasy VIII
Runner up
Final Fantasy X
To me all of these are horrible twist. Zero Time Dilemma might be the one that left me the most perplexed. It's also to me a lame twist that just exist for the sake of the game having a twist. It's like M. Night Shyamalan. A series known for having twist so they had to have one for the last game even if it was unimportant and lame.
The Mass Effect and Star Ocean twist might have both ruined both those series.
That Heavy Rain twist was straight up BS.
Star Ocean III Til the End of Time
The entire series is a video game. Yeah it's true for us but the actual canon plot of all the games is a video game inside a video game. All the characters in the series are just AI and not real people in their world.
Mass Effect 3
The reapers are just tools used to reset the galaxy because supposedly synthetics will wipe out organics and the most advanced civilizations at the time of the reset are condensed into reaper form to preserve them.

Heavy Rain
Shelby was the killer though he is a player character and doesn't give any indication of this until the reveal of the twist.
Final Fantasy VIII
We're all from the same orphanage but using guardian forces makes us forget but Irvine actually remembers cause he never used them until he met us but he says nothing because nobody else said anything.
