Revealed in June, Demo Play will debut in the upcoming New Super Mario Bros. Wii, which is scheduled for a Christmas launch. The new feature will let the game take over from the player and play itself through particularly tough areas, allowing them to avoid the frustration and, one would imagine, sense of accomplishment that goes along with having to struggle through the hard bits. Nintendo mastermind Shigeru Miyamoto said other Wii games would support Demo Play in the future as well.
It now appears that the Wii won't be the only Nintendo system boasting this feature. According to an article in the Nikkei, it will also be offered in "upcoming portable titles," although no specific games were named. The report says the new system is suitable for "high speed action games."
Demo Play is designed to help attract new and casual players to Nintendo's various titles by offering them an "out" when they bump up against rough spots in games, without making things overly easy for gamers who enjoy the extra challenge.
