I remember playing a game on the Amstrad 6128 in the '80s or early '90s. It was a space adventure with at least part of the action flying through space and shooting alien ships.
There was an option to view the space-fight scenes in red-blue separated 3D and I think the game came with a pair of 3D glasses. The stars (or possibly just space dust!) were rendered as two separate dots, one red, one blue to simulate the 3D effect as well as the enemy ships.
The "stars" would zoom past your ship as you were flying. I seem to remember that it had full 3D movement, à la Elite, although it might have been more limited than that. What's the name of this game?
