GameNTrain author Peter Thomas writes: When the 3DS first launched, fans rejoiced while those not in support of Nintendo claimed that the glasses-free 3D feature was ‘gimmicky at best.’ While I tried my best to fend off the masses, there was no denying it: I barely used my 3D feature on my games. Out of the 10 games that I own, I probably played four with it on, and two I could have probably played without. Even when I had it on, I usually only had it at half strength since having it too high would make my eyes cross. I get it: it was a neat, revolutionary feature that wasn’t big, but Nintendo wanted to make it big. That’s what they do. They revolutionize. They don’t create gaming consoles; they create eras.
