I have noticed that in the larger version of the 3DS(xl) the 3D is much much better. BUT I do also know that I can't for the life of me turn that 3D up much at all. It hurts so bad, but then again I also have a problem with HD Tv's and 3D movies sometimes. I think it may have something to do with a astigmatism that I have because one eye has to work twice a hard as the other. x.x;
