Should Wii have “Achievements?

I posted the follwing over on Nintendo’s official forums and it seemes to generate some interest so I have decided to also post it here:

I personally love the whole achievement idea that XBOX 360 offers and I think that it would be a great idea if Nintendo would implement something similar in their upcoming Wii system. There is also a rumor now that PS3 will be doing something similar to XBOX’s achievements. Think about it, wouldn’t it be cool if Nintendo would reward you “shines” or “stars” for beating certain games, then you could take those points and buy VC games. What do you guys think?
