The Nintendo 3DS boasted that it would have glasses free 3D and that it would also have higher end graphics despite being a portable device. Now the 3D was surely a gimmick, the slider was there for you to control how much 3D depth there was or to turn it off altogether.
Most people would use the 3D for a few minutes but would turn it off when it came to serious gaming or when they started to feel a bit dizzy. But in Satoru Iwatra's financial briefing for this last quarter, the Nintendo President says that he believes that there will be future 3DS titles that won't even use the 3D feature.
"I think there could be a Nintendo 3DS software title which does not use the 3D feature at all, and I believe Nintendo will develop such software. Instead, other features of the Nintendo 3DS should be focused on. It might be a communication feature, or other functions (such as the gyro sensor or the motion sensor). The important thing is that each respective software title has its own characteristics, and appeals to the consumers in a way that fits the software."
Wait, the system is called the 3DS and some games won't even have a feature that's in more than half of the system's name? Sure it's a gimmick that probably won't be used most of the time but don't just remove the feature from the games. If I got a 3DS, I probably would have the 3D for the most of it but it's nice to know the option is still there.
Iwata then goes on to say that he's not worried about the "novelty of 3D" wearing off and that the big upcoming titles such as Super Mario 3DLand and Mario Kart 7 will all the 3D wazoo.
