And I hear you on the impact on 2D games. Man, the 3D remasters of Sega classics on the 3DS are amazing and it sucks that they will remain trapped in there indefinitely.
And yeah, emulation. You can get stereo output out of it right now, but it's just such a hassle even if you have the hardware. You can do it, but the 3DS was so seamless that it just isn't the same thing. Pulling that thing out of mothballs if you haven't played it in a while is immediately magical. It still looks sci-fi because it just works. Having some convoluted emulation-to-VR setup or whatever is fundamentally different.
