Kotaku points out a recent patent filed by Nintendo which automates gameplay unless the user specifically chooses to play a particular part of the game. Quoting: "The new system, described in a patent filed by Nintendo Creative Director Shigeru Miyamoto on June 30, 2008, but made public today, looks to solve the issue of casual gamers losing interest in a game before they complete it, while still maintaining the interest of hardcore gamers. The solution would turn a game into a full-length cut scene of sorts, allowing players to jump into and out of the action whenever they wanted. But when played this way, gamers would not be able to save their progress, maintaining the challenge of completing a game without skipping or cheating."
