I love the concept but after a few hours of playing in 3D I got a major headache. I now play in 2D all the time. I used to own the original 3DS and I've got to admit, the screen is much bigger than I thought it would be. I'm satisfied with the overall product. It is, however, very expensive. I paid the full price when it got out only to see the price drop a few months later but Nintendo is used to ripping off it's customers. The case is flimsy; I'm an adult not playing very often and there are broken parts. The buttons stop responding properly very fast.
Good product, bad company.
