What is the Wii's most played Need for Speed game, based on "Total Hours" reported played?

Can you guess which one is the most played by total hours reported?

Did you know the Wii had six Need for Speed games released for it? Well, at least six in the United States. Six. 1, 2, 3, 4, 5, 6! I didn't realize there were so many Need for Speed games within 6 years, much less six Need for Speed games on one console!

The image above shows the six Need for Speed games that released on the Wii in the United States, at least that I'm aware of. They were: Need for Speed Carbon, Need for Speed: Pro Street, Need for Speed: Undercover, Need for Speed NITRO, Need for Speed: Hot Pursuit, and Need for Speed: The Run. There could have been another that I missed, but these are what I found in my research.

Now, if you're a Wii U owner, like myself, you may be aware (or not) that Need for Speed: Most Wanted U is releasing for the system today, March 19th. While it will be the Wii U's first Need for Speed game, if the number of Need for Speed games on the Wii is any clue, Most Wanted U won't be the Wii U's last.

Before you go off and start playing Need for Speed: Most Wanted U though, what is the Wii's most played Need for Speed game based on the total hours reported played from U.S. Wii owners? Brew yourself some coffee, and let's take a look!
