What Games Would 3D Add To?

The notion of 3D in gaming has been met with skepticism instead of anticipation for the most part, but I believe there are some games that would be enhanced by a 3D experience.  What would be the top game(s) for you that sound awesome in 3D?
 
Mine is Super Mario Galaxy.

Nothing comes to mind. 
 
3Ds gonna be a gimmick, might as well have some original gimmicky titles.

This is kind of being discussed here: I love how nobody cares about 3D  The thread creator, ShalashaskaUK666 asks...

"What dyu guys think? What games could it be implemented into, what would be a cool use of this technology that would sell you on it? I personally would love a combination of 3D and Natal tech to recreate the Heavy Rain office in real time, so you can do all the hand motions jus like Mr Jayden (you'll know what I mean if you've played it :D)"

The only ones I can think of are artsy games like Flower and the Katamari games.

Left4dead 2. Then again if I wanted 3d, I could totally do that with nvidia 3d vision.
