Hunting about the internet, I came across a video of Legend of Zelda: Ocarina of Time being played on a 3DS and I have to say I’m very impressed with what they have done. The narration is in German but I can easily point out the highlights you can discern from the video after the jump.
As you can see in this seven-minute video, the 3D capabilities of the DS allow the system to be used in ways that would probably be impossible or at least incredibly complicated with technology utilized by most other consoles preceeding the 3DS. As you can see at 1:20, you can actually look in all directions by physically tilting the 3DS, and the graphics of the game have also been heavily improved.
Tilting the 3DS itself also gives the ability to manually aim (according to 5:15 onwards), which is a very clever means of handling first-person aiming. Any console gamer will tell you that first-person controls are completely hit and miss, having to deal with options like sensitivity, axis-inversion, and the like.
As is common in DS games due to the touchscreen, things like menus and controls are controlled largely by the lower screen, which greatly simplifies the controls that would be used by the original N64, and makes the screen far less cluttered. OOT’s port to the 3DS clearly puts the 3DS’ motion control, 3D technology, and touch screen to impressive use. All these improvements make for far smoother gameplay, and is simply an amazing improvement. Great, now I want a 3DS more than ever.
