Although the battles and movement are the same as in previous titles, the backgrounds and scenes have been redesigned to showcase the 3D capabilities of the handheld system.
Nintendo quickly redesigned the wriststrap so it stayed securely around your wrist and realized that they needed to reestablish gamer trust with a free Wii plastic condom/cover.
Nintendo exchanged those straps and made the material thicker and redesigned the clasp so it would stayed closed better.
The redesigned Nintendo DS is the same shape and features almost the same button layout at the current model.
