I'm going to have to push back on Soma being shocking...
Is that twist that people thought you could cut-and-paste your consciousness, so the player character would leave on the Ark? Thought it was apparent through story details that consciousness could only be copied and that you are not the exact same character from the opening in the modern day.
Granted, I'd run into that sci-fi concept before, so it's not like I figured it out/came up with the twist on my own. Mainly curious lf Soma was the first time people had been exposed to that idea, or if there's some element of the twist I'm missing.
Still a great game and story, btw. The player character got hornswoggled, but not me the player, so it didn't detract from the story, imo.
