The path of those projectiles is also noteworthy, according to Sakurai: "In standard shooters or FPS games you see the bullet travel to its destination and it's just a dot because it travels in a straight line," Sakurai explained. "But because of 3D technology you can use arcing shots and get a sense of a bullet travelling with real depth."
Sakurai also mentioned that he had an indirect role in the system's development. "Early on, Nintendo were soliciting lots of feedback from within the company and from me. And I had very specific requests from Mr. Iwata in regard to what my ideal picture of the device was, etc." He didn't say what his specific recommendations were, but he did subsequently call the combination of the touch screen and the Slide Panel "very important" for 3D games.
