Implementationen af den såkaldte super guide i New Super Mario Bros. Wii har modtaget blandet kritik. Nu går manden bag Shigeru Miyamoto endnu engang i detaljer omkring udviklingen af guiden.
Miyamoto fortæller, at guiden oprindelig kom frem efter tre dødsfald på samme bane, men ham og udviklerne blev enige om, at det var for ofte. Derfor besluttede man sig efter en række tests for, at den skulle komme frem efter otte gange.
"Originally I wanted it to be viewable after failing at a level three times, but that was too few. You'd wind up summoning the Super Guide block even when you're playing normally, and the testers and I both thought that was just annoying! So after some trial and error, we settled on eight tries. That's about the point when people start to think 'Man, this stage is kind of hard' and get a little frustrated. If they watch the Super Guide, maybe then they realize it's easier than they thought. We want people to get though this on their own power first, so that's how we decided it in the end. In Mario 3 there was an item, the P-Wing, that basically let you skip a single stage at any time. I figured that since that game has 80 levels or so anyway, it'd be nice to let gamers take a pass on at least one or two of them; then, once they beat the game, they could go back to those stages and try them again. In New SMB Wii, we took that to another level." - Shigeru Miyamoto
På trods af super guiden er New Super Mario Bros. Wii blevet kaldt for et af de sværeste Mario-spil nogensinde.
