Wii - Dust is back on

The dust is now starting to settle back on the Wii, I think I need a new game for it, I only have Mario Party 8, Wii Sports & Wii Play. I also have a few downloaded games from the Wii store but I forget what? I have not completed Zack & Wiki & I did enjoy playing it, maybe I should get that again? or go for a Super Mario Galaxy game? Don't know I'll have a look to see what I can buy on-line later
