As far as I am aware no one has ever made a proper holographic game, as in a game with parallax on the display.

Most true holographic displays are still under lab conditions with high power lasers, expensive optics and precision setup. Maybe someone at a lab has hacked together a game of sorts though.

You could probably create a sort of holographic game with a lenticular display. You would have slight parallax with a couple of views, it would be quite rudimentary though but a fun project.

Lenticulars generalise to full parallax with tiny circular lenses instead of cylindrical ones. The only thing preventing this from being a viable "holographic display" is the resolution/DPI required of the active display technology. When this eventually comes to pass (and it will) it will be a revolution like VR, but better.
