Shigsy has revealed that Mario's latest side-scrolling platformer will have a "demo" function which allows the cpu to take over if the player is struggling to get past any part of the game.
" In New Super Mario Bros Wii, if a player is experiencing an area of difficulty, this will allow them to clear it and then take over when they are ready. We are also looking into this for future games ".
Of course this is entirely optional, but is giving people an easy way out a good idea?
