We've already heard of BioShock being a trilogy, and we' ve got BioShock 2 still having an on-off relationship with the subtitle "Sea of Dreams" before its release later this year. And yet we've already got some hints/speculations about the setting of the last iteration in the trilogy: Rapture once more.
UK's Official Xbox Magazine is reporting that 2K Creative Director Jordan Thomas let mentioned how BioShock 3 will most likely remain in the city of Rapture. I give the floor to Mr. Thomas:
I think Rapture remains fertile for as much expansion as a team sees in it. I absolutely believe that there might be future games set in Rapture in whatever time period, but I would also say that I think that the BioShock brand is big enough that it could evolve.
Furthermore, he also talked about the element of decision-making in-game, putting the motive in the choice that players will make:
I am very interested in allowing the player more control, more intentionality in the way the game is resolved. In BioShock 1 the game had a pretty binary ending and there was a point where it was irreversible and you were put into Box A or Box B. This time around, my goal is to make sure that along the way when the player is making choices that are going to resonate in the end-game, they're aware of it every step of the way.
