Prophecy2k answered part of your question:
3DS has features that makes it obvious for users to notice the difference right away. For example, without even looking at the actual games, they can tell HDTVs has stereoscopic 3D that requires 3D glasses, 3DS games don't need glasses. Whether 3D display changes gameplay, we will have to look at individual game titles to find out.
For NGP-savvy or exclusive games, the differences are less obvious. That's why I mention Sony and developers will have to think/work harder to achieve that perception difference.
The concern that the NGP unique features
may not be as apparent or as easily communicated to the consumer
from the package is something I have also expressed in these very forums and the consumer
may need to have first hand experience with the product to notice. This is mostly marketing related but that is irrelevant to what it can
actually offer.
3DS is still a DS slapped with 3D. So far there is no title announced that makes use of the 3D screen to differentiate gameplay and they didnt communicate/explain during any of its announcements how 3D will change gameplay experience.
It is
always about the game design regardless of platform and both the NGP and the 3DS have the right foundations for that and they arent much different in that respect.
Not sure what you meant by "the first". I think NGP will need to differentiate from both casual portable gaming as well as core home console gaming. With Playstation Suite, the line between cellphone gaming and NGP gaming may blur.
By the first I was referring to the argument that the NGP doesnt have much to differentiate itself from PS3/console like experiences and traditional gaming, but you havent exactly supported this with arguements. You victimize it for that but the hardware design is not a problem. It has the right hardware,
Its only up to the developers from there on to design the games that will take advantage of it appropriately. You cant argue with the fact that this is game design dependent. Why dont you just wait and see what developers will do instead?
Regarding your argument that the NGP should differentiate from the core and casuals, I am not sure it makes sense. Its impossible to differentiate from both when everyone targets those two segments and these are the two segments that consist 100% of the market. There is no other else left anyways. They dont have to differentiate
from those two. These will always be the targeted segments. The difference is that they will have to differentiate
for those segments by enriching the experience offered to them. The 3DS and the NGP are in the same situation (if we ignore past success carried to the present and price differences) and both will face the same challenges from the iOS (and Android) game competition which is everyday devices that happen to play games and at cheap prices. Hardware adoption for the latter is seamless and is the biggest advantage that these devices have compared to gaming dedicated devices. Who doesnt need a phone these days?
