I know the kind of company Nintendo is (gameplay oriented), and they haven't steered me wrong yet.

Damn right. And Double Dash - I love that game. I've already destroyed it in GP mode, but it's still hours of fun with my 9-year-old brother and his friends, or my 30-year-old buddy from work. It doesn't matter how old you are - it matters how much fun it is to push the buttons.

Oh, and if you've got yourself a Broadband Adapter, you may want to check this out.
