I had a 3D setup at the end of the 90's. Nvidia shutter glasses, pc hooked up to a CRT projector with 72" screen. It was pretty awesome in the beginning. 3D added a lot to Descent 2, it became very easy to dodge the slow moving projectiles. It worked with most 3D games at the time, yet after a month the novelty wore off and I stopped using it altogether a couple months later. The higher resolution and better frame rate of 2D won over the no longer new 3D effect.
Now I'm not all that eager to upgrade again. At the time it only set me back $40 for a set of wired glasses since there was no display lag to compensate for with the old CRT technology. Nowadays you need to buy a new tv or new projector to get the same effect again. Progress :/
If 3D is still around this time when I'm ready to buy a new tv or projector then I'll probably pay a little extra for a good 3D one. It does add to the experience. I really needed 3D in Dark Souls when getting knocked off the ledges in Sen's Castle for the 20th time by misjudging the position of the swinging axes. I imagine it should help in 3D platformers too. I'm never a 100% sure if I'm going to land on or next to the platform I'm aiming for.
