Well, the fact that not everybody has good stereoscopic sight should mean that, on accessibility alone. But I've also never bought into that particular criticism.

I mean, I also don't have a useful game mechanic for super detailed graphics and you don't see me complaining about games looking good. I thought playing through little dioramas looked great and was super fun, and that was all I needed. When the DS had its phase of shoehorning touch controls on everything I found that extremely obnoxious. Not every gimmick needs to be at the core of every game.
