Buying walkthrough book at the brick-and-mortar bookstore is usually better for those playing racing or first person shooter games.
So is buying a physical book from the store better than reading an online-only Wii game walkthrough?
Try and only utilize the Xbox walkthrough when you get stuck.
This walkthrough also specifically mentions some of the routine diagnostic procedures done in the office, including a 3-D digital x-ray machine that minimizes actual patient exposure to x-rays.
After all, no Nintendo Wii walkthrough would make any sense if you did not understand how to use the Wii Remote and where the different buttons are on the controller!
