In a video interview AusGamers conducted with Irrational Games' Ken Levine, the revered designer spoke about the team's lengthy development process, not only revealing that "the script of BioShock One could easily fit into one of our levels in Infinite", but that in the editing process they stripped back so much stuff, it was essentially two games worth.
"I can’t tell you how much of this game... we probably cut two games worth of stuff out of the game, and I say that just in terms of content," Levine told AG.
"Finishing and polishing is a whole other matter, but this is just the raw amount of content, we cut tonnes and tonnes of stuff."
He also talked candidly about his relationship with the Elizabeth character saying that he's "probably a little bit in love with her" but that he "has to be" adding that "she's the heart of the game". He also openly talks about going into a depression after shipping the first BioShock, being finished in his capacity now on Infinite, his thoughts on DLC, multiplayer, voicing and fleshing out the player-character, Booker, and much, much more.
This is a meaty interview, but one well worth a read or watch for fans of the series, Irrational, or game development in general.
