Fair enough, not saying it has the possibility of being awesome to everyone but the majority of people I speak to IRL about 3D, be it gaming or movies, will say "I don't like 3D" and when pressed they've seen one film in the cinema or something, which is not enough time for your brain to adjust.
There's a big difference between how 3D is achieved with a projector and how 3D is done in video games. Projectors don't render images - everything's already on film, so as long as you have film made with two angles, you're golden. With games it's different - any form of 3D requires double the frames which often times negatively impacts performance. If it's a shutters system, you lose out on framerate
(for obvious reasons) and it's tiring to your eyes due to all the flashing of the shutters. If it's a parallax barrier like on the 3DS, you're entering jaggies country the moment you switch the feature on since half the pixels have to be dedicated to one eye and half to the other, not to mention that double the rendering means far worse framerate. The only
proper 3D solution involves a headset like the Oculus Rift which performs all the necessary FOV transformation, but utilizing it requires pretty beefy hardware since you do need the extra framerate like in other solutions
and the resolution isn't all that great anyways, even after so many revisions. We're just not quite
"there" with 3D yet, but if I were to bet on something, I'd bet on the Oculus and similar devices, and even then I think it's totally a gimmick and it won't retire the traditional
"sit on your couch/in your chair and just play" gaming.
