Gaming has gone through many changes over the years, but 2008 was most definitely when the self-improvement and non-gaming software genre came into its own.
Although traditional titles continued to break new ground and fare well commercially, any advances made were comparatively small to those made in the self-improvement market.
The successful launch of games such as Wii Fit and Cooking Guide and the introduction of more practical products like Atari and Ubisoft's driving theory test titles has expanded the scope of the genre. Meanwhile, the continually strong sales of the Brain Training series inspired a significant increase in similar, less conventional games hitting the shelves.

The NPD Group has revealed the top 10 best-selling exclusives in the U.S. since 1995, and Nintendo holds all 10 spots.
Nintendo has always had the most mass appeal, my Mother would play Mario.
There's landslides and then there's this. Wouldn't be surprised if the top 50 was mostly Nintendo games.

VGChartz's William D'Angelo: "Today we take a look at the top 10 best-selling games for yet another platform. Up to this point we have looked at the original PlayStation, the Nintendo 64, the PlayStation 2, the original Xbox, the GameCube, the Nintendo DS, and the PSP. This week it's the turn of Nintendo's most popular home console, the Wii.
The Wii is the fifth best-selling video game platform in history and the third best-selling home console in gaming history. It is also the best-selling home console not released by Sony. It sold 101.18 million units lifetime."
Just like the DS list, every game on the Wii's list has sold over 10 million. Not even PS1 and PS2 did that. That's very incredible
