BioShock's story was initially very, very different. At one point, your character would have been rescuing someone from a cult. Later, in 2004, the idea was you'd be exploring an abandoned World War II laboratory on a tropical island, the sinister genetic experiments of which had become Splicers, Sisters et al. "A lot of the game design elements stayed the same," explained creative director Ken Levine. "Story changed radically, but gameplay always comes first
for us."
