Is it one of the early Wiis? If it is you can use it as a Gamecube. Epic Mickey I heard is okay, not great.
I honestly don't use the Wii either. I borrowed Metal Gear Solid Twin Snakes and I may get Legend of Zelda Wind Waker for it.
You can also use the Virtual Console and play vintage games on it. That's how you get Majora's Mask and Ocarina of Time.
