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.

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.

• BioShock to be a trilogy; movie to be released with third game
