Aparently you dont have experience with how FPS works with a touchscreen, specially on the DS.
The lower DS touchscreen acst like a mini-mouse, and the d-pad acts like the AWSD keyboad keys. The left trigger is for shooting.
All the action is happening in the upper screen.
So, you aim with the stylus and move wth the d-pad, just like a keyboard and mouse. Much faster and accurate than double analogs.
Try Dementium, Metroid Prime Hunters, Brothers in Arms, Call of Duty... or coming soon Core, Moon, Duke Nukem DS, etc.
Check the video and you can see how FPS works with a stylus... is the closest to a K & M
The DS is way better to play FPS.
Hahaha okay 1 game. In Metroid Prime Hunters and others, jump, roll and a ton of other commands floating around the sides and bottom of the touch screen. Chances are that with your eyes on the top screen your going to slide your stylus or thumb strap over "jump" or "roll into a ball" or some other command when all you wanted was to look in that direction.
If you slide the stylus over the buttons, nothing happens. No need to worry. You need to tap the icons.
And to jump in Metroid Prime you need to double tap the touchscreen. Is very easy to play.
