When I first got my Wii, I bought and received a handful of games that I could register on Club Nintendo and get "Coins". I looked a few times with the 220 coins I had, mostly stickers, posters, screen savers and other stuff I had no use for.
Now you can actually download Wii Ware games to your console with your coins. So today I downloaded Super Mario Kart for 100 coins, this game and 3 others are available until Jan 10. Thought about downloading Mario Vs. Donkey Kong but I think I may wait to see if other games become available in the future. Xevious & Fluidity are the other two games right now.
So maybe this will get me to play my Wii a little more over the holidays!
