Idk, I suppose you can argue that the binary morality system of the first BioShock was integral to the franchise identity, considering the time it came out and all, but I don't hate that Infinite has one definitive ending to the story it wanted to tell. In fact, given the game's emphasis on tropes and meta commentary, I'd imagine that setting a story in a universe with infinite possibilities and then removing the "choice" from the player to influence the ending was done deliberately. However, it's been a decade since I played it, so I could certainly be misremembering some details.
