A truly nonlinear story would be written entirely by the actions of the player, and thus remains a difficult design challenge. As such, there is often little or no story in video games with a truly nonlinear gameplay. "Facade", a video game often categorized as an interactive drama, features many branching paths that are dictated by the user's text input based on the current situation, but there is still a set number of outcomes as a result of the inherent limitations of programming, and as such, is non-linear, but not entirely so.
