The Wild West review at IGN.

"The Nintendo DS could be a really fun system for light gun games. There are a couple titles out that try that and they do a decent job. But just because the touch screen lends itself well to tap-shooting doesn't mean it should be used for every type of shooter, especially if the developers seem to know nothing about shooters. The Wild West, a western style shooting mishmash by Happy Happenings, proves that a developer can take a seemingly simple idea and screw it up in every way."
