If you’ve got a 3DS, and you’ve got an Internet connection, there’s no reason to not have downloaded the latest system update and pulled down 3D Classics: Excitebike from the Nintendo eShop. It’s free, after all.
If you haven’t quite wrapped your noodle around what Arika’s Forever Blue for the Wii is yet, this extended gameplay clip might shed some light. As you can see, it’s all in Japanese, as the Western version (Endless Ocean) won’t be released for months. Despite it’s high Famitsu rating, I have a hard time believing this is going to be a purchase for me personally.
