Look, I play lots of FPS shooters..................on the PC, with a keyboard and mouse.
There is just no other valid alternative to play an FPS.
One that gets close enough would be the pointer abilities of the Wii remote ( but you loose speed and accuracy ) and the other one, even better , is the NINTENDO DS TOUCH SCREEN.
Yes, it might give you cramps and might be uncomfortable to some, but it's undeniably the next best thing after a keyboard and mouse for FPS.
You just get an unprecedented accuracy and speed with the touch screen
Why would I want to sacrifice that for a second analog stick ?
FPS where never meant to be seriously played on a console.
Goldeneye on the N64 was and still is a breakthrough on the genre because had FPS controls tailor made for the uniqueness of the controller.
After that we sort of saw EVERY other FPS on a home console using a dual analog setup, but even games like Metroid Prime , proved that the second analog doesn't really make for a better experience. It is actually awful to control an FPS like this , and it becomes nearly impossible to do so without auto-aiming.
Let me tell you something: Auto-aiming sucks ! ( now go and argue with it, non hardcore FPS player ..).
Also, as I stated before, conveniently having a second analog on the 3DS, would open up the possibility for developers to lazily port games from the PS2 era, no doubt about it.
And it wouldn't be done right anyway.
I'll explain: Most of us have two thumbs
, now if both thumbs are on the analog sliders ( if like you say they should put a second one in it ), then the only other fingers free to perform actions would be the index fingers on both hands.
That might work fine on a Dual Shock like controller with 4 shoulder buttons (L1 L2, R1 R2 ), because you could map basic actions like shooting, duck, jump and weapon selection or secondary fire to it, but on and handled, 4 shoulder buttons are unheard of and at the least very difficult to implement given the nature of the small proportions, therefore you would be left with an half-assed control scheme ported from the days of PS2 with cumbersome combination of thumb, index fingers and touch screen controls to even perform the most basic actions.
My other point is also that ever since the days of the original GB, the difference in screen resolution or control scheme, always forced developers to create new content for Nintendo handled to fully take advantage of the hardware.
And that has been a key in the success of Nintendo and put it currently and more then ever on top of the handled kingdom.
Other contenders where available at the time, like the atari lynx and sega gamegear , but they all failed because they were to ambitious ( besides they were suckers for battery life but that's a different story ) and had such high graphic capabilities ( again compared to the GB ) that developers were simply porting games from home consoles, and that was a huge failure ( even to this days, that's what happens to most PSP games, and that's how the DS is so popular and highly regarded for it's diverse library of original titles not found anywhere else.
So ,these are the facts that lead me to believe that Nintendo are once again on the right track and the 3DS will be even bigger ( in terms of sales and popularity ) then the mighty DS, even without a second analog stick ( and again, for the solely purpose of camera adjusting the motion sensors would make up for it quite egregiously ).
