I've tried it. It pretty cool in the beginning and it really gives you the sensation of 3d.
Bad things:
Everything is in shades of red and blue.
You have to concentrate and get used to the 2 pictures.
You lose performance because it has to produce two pictures at once.
It doesn't really feel like a concrete picture, a little frustrating.
Dark picture.
Everything bright is red and dark is blue.
takes away from the game's emersion.
I tried it, thought it was cool, but I think its better to experience the game without picture frustration.
