Perhaps jokingly, Levine said that at one point he and the entire team questioned whether the scale of Elizabeth was just too grand to capture. Building a completely authentic artificial partner that reacts to player interaction with both the character and the world is no simple task, and even great minds like those at Irrational can be plagued with doubt. Thankfully, Levine decided to create a secondary team that would work exclusively on Elizabeth's AI and her interaction capabilities to make her as polished as she is for launch.
