If Nintendo really wants to improve people's lives they should forget about Brain and Sight and Face Training. Much more useful would be Lifestyle Training, a game that teaches you how to live and look like the people in the promotional photographs for Brain and Sight and Face Training. The exercises would train you how to have excellent hair and layer casual sportswear effectively. You would have to practice facial expressions such as rapture, astonishment and boundless joy for when you're playing games. There would be a special bonus mode about how to live in Shoreditch in a flat full of hardwood floors and things made of white.
But no. Nintendo thinks we're still labouring under the impression it's more important to be clever than look like a Hollyoaks, so they've gone and done Professor Kageyama's Maths Training: The Hundred Cell Calculation Method. If that doesn't get you excited, nothing about this title will.
Maths Training features a Daily Test mode which is basically Brain Training except all the exercises involve numbers. You hold the DS sideways like a book and write answers on the touch screen. There are addition and subtraction sums, flash card exercises where you have to identify the number of objects shown and so on. You're judged on how fast you respond plus how many correct answers you give and awarded medals accordingly.
