Yeah, I think my recommendations are off based off what you've said. The story/choices/characters/roleplaying is what I honed in on.
Based on what you've said, I want to suggest the Bioshock series, which I haven't played, but everyone in the world tells me I should play Bioshock because I love fallout so much and had fun with Dishonored. Another interesting one, but forewarned had a very abrupt and unsatisfying ending was Rage. The gameplay was awesome in Rage, and John Goodman voices the first dude you meet.
I never got into it, but Metro 2033 *might* be fun as it is like Fallout but more realistic/sim-like. There is also Wolfenstein, which I never finished and always say I am going to play again.
