As the numerous user pictures in this thread show, you don't need the stand. I play with the stylus controls, I play holding the system in front of my face without the stand, I play with 3D all the way up, and it plays just fine. The controls are wonderful. If you need to balance the system, rest it on your palm, your pinky or hell, even your leg. This isn't rocket science, for chrisssakes. It took longer to learn and grow comfortable with dual analog back in the day than it did this control scheme, and this control scheme is functionally superior, absolutely.
Much ado about nothing, I say, and people skipping because of this overblown bullshit are missing a modern-day Nintendo classic packed full of fantastic characters, moments and awesome production values. Instead they should open their mind and not expect to be a master of a new scheme right from the first minute. Then they can actually ease themselves into learning the game's unique rhythm and see just awesome the controls are, which is to say VERY awesome. Hell, sometimes I boot up the game for the sheer joy of moving the camera, it's that fun.
And word to the wise: Max out horizontal and vertical aiming speed on land and in the air, and max out reticule stopping speed. You barely need to "swipe" the screen in this fashion. Super-precise for righties and lefties. Easy. Effortless. And then the ground game will begin to show its depth, especially in multiplayer, which is incredibly addictive, btw.
