Nintendo keeps things simple with the Wii. It comes in only one version, which, at about $250, costs significantly less than the Xbox 360 or the PlayStation 3. The Wii also includes one pleasant surprise, a simple but infectious game called Wii Sports that lets users get a feel for the system's wireless controller. You can swap the remote back and forth to play golf or to bowl, but if you want to play tennis or baseball head-to-head, you will need to purchase at least one more controller. Find Used Wii Consoles.
