Like others have said, the 3D is part of a set of features (alongside streetpass and spotpass) that make the product come alive, and make it unique. These are its USPs (unique selling propositions).

In terms of 3D's game-wise appeal, I found that I had a hard time playing SM3DL with the 3D turned off. I have much better depth perception with the 3D on. Re:R, I played the demo and the immersion is much stronger with the 3D on. However, at times I really need to concentrate, so I have to turn it off (same for SFIV, it's never on with that game). For OoT, the visual experience is just so much better with 3D on.

Business-wise, it's a very tough call: there are trade-offs. On one hand, it required twice the performance of a 2D device, as two images are being produced at once to create the 3D effect at a higher resolution than the 2D (not 100% sure about this, someone correct me if I'm wrong). Also, the SDK and API had to provide tools for this to work, and is a core part of the 3DS API architecture. Odds are it made the costs a little more expensive, let alone the screen that needs to be compatible with the 2-input signal of stereoscopic 3D. Any unique new HW does not benefit from the years of amortization of research of a HW piece that has been produced for years (by foxconn). That's another big one. Ultimately, what happened was the 3DS struggled to hit mass appeal until a massive price-cut was made. Luckily the 3DS will have sold at a loss for only 1 year over a 6 to 7 year lifespan. Was that compromise worth to offer the USP the 3DS offers? Ultimately, I believe so.

A great decision for the 3DS. I've owned mine for 6 months and was fully expecting the 'Wow!' factor of 3D to have worn off after a month or two but it's still there for me personally.

I think the main problem is that there's no 3D movies out for it.

Otherwise, 3D was a great idea to make many games look better than anything available on PSP Vita.

They show with the Video-application some 3D-made movies. Render-movies like Big Buck Bunny or puppet movies like Shaun the sheep. Nothing really big, but the 3D-short-movies are there. Or do you mean long movies? How should they delivered?

Funny thing is, at the poll half as much people vote for Yes (it was a bad decision) than for no. But the people thinking it was actually a bad decision seem to remain silent.

And most people agree with my thinking, that 3D is a point that makes the 3DS distinct to the DSi. But does it need such thing to sell? Did the PS2 had anything to offer other than being a faster PS1?

That's because they vote before reading all the posts ;)

Hopefully, this thread opened their eyes.

It's not the #gamechanger we thought it would be but it's still awesome. I was watching the Kid Icaru Medusa video on Nintendo video last night and I had to pause and look at it. Lady Palutena was popping one whole inch out of the screen. It 's still available on Nintendo Video--pause it at 1:28. It's a sight to see!

Of course, there are down sides but Nintendo couldn't have known. At the time, 3D was looking like a definite no brainer. I blame Avatar.

The 3D video service, if existent (I didn't get it to work yet, I'm in Canada), is lackluster at best. We need something like youtube, but 3D. I think alot of folks were expecting that, so if 3D is to be made more mature, that definitely has to happen.

Facts?  You make your own conclusions and state it as facts....

I don't use it, but my friend likes it a lot so i think its needed and all that.
