Just thought this was odd/funny:
Beginning with the upcoming New Super Mario Bros. Wii (due this holiday season), players will be able to pause a game during a particularly difficult level and let the game take over to complete the level. Press a button at any time to resume playing. This will help reduce barriers of entry for new or younger players â€“ without purchasing a strategy guide or resorting to websites that list cheat codes.
When I first heard about this feature, I thought that the game would play-through the level by itself to show you how to do it, but wouldn’t actually move you through the game.
Nintendo even got a patent on it.
