As the saying goes, if you can't beat them, make game controllers for them. Or something like that. Nintendo, who has seen mobile gaming shift from dedicated portable consoles like its DS series to touchscreen-enabled smartphones, may try to bridge the gap.

Still, there are a lot of games meant for diamond pad navigation, analog control sticks, trigger shooters, and more.
