If the next Nintendo handheld had dual sticks, how would their games change?

[Soundwave]

Monster Hunter, Luigi's Mansion, Mario 3D Land, and Kid Icarus just off the top of my head could use a second analog stick. Other Nintendo franchises like Metroid Prime as well. Obviously third party franchises like Resident Evil, Metal Gear Solid, NBA 2K, Call of Duty could use it too.
