I did a bit of some very quick research on Amazon JP to check to see how much of a deal this is.
A Wii, currently on sale, is 18,500 Yen.
A new game (I checked Super Mario Galaxy 2, since that holds in value) looks to be 5,800 Yen.
A Classic Controller Pro is on sale for 1,800 Yen.
Right there, the bundle exceeds the value, and you also get the 1000 Yen Point Card and a USB stick (how big is it?)
So it's not an amazing deal, but it's still worth it, unless you wanna take risks and buy used on the console and the controller
Edit: Just saw Post #3. If that's so, then it's actually a really good deal.
