Nintendo's Wii was a pretty appealing system for developers who were working on third-person shooter games at the time. On the one hand, the Wii wasn't as obsessed with realistic graphics as the Xbox 360 or the PS3, which meant these games could have fairly unique art styles and visual aesthetics to set them apart. Of course, there was also the motion controls, which were seen as groundbreaking for the time, especially for shooter games where they could add an extra layer of immersion to the experience.
