Nintendo's 3DS has been out in the wild for a week now and reactions to the glasses-free 3D effect thus far has been mixed. In the GI offices alone, while some of us felt it was a cool effect, others turned it off after a short period of time. All eyes react differently to the technology, so I'm curious, if you've had a chance to play 3DS, what do you think of the effect? Do you think it adds to or detracts from the gameplay experience? How about the 3D experience with PS3 titles? Sound off on 3D in the comments section!
