The unofficial cartoon guide to He-Man and the Masters of the Universe features many more abandoned episodes!
"Video Magic"
An evil inventor lands on the planet Eternia, bringing strange computer games from distant worlds. The games become the rage of the royal palace, until one game takes on a life of its own. He-Man and friends are swept into the game, where they must wage battle with strange computer creatures from the dimension of Videola, where Skeletor now rules!
* Legally I should say that David Wise did NOT write this episode. This is merely an example of how the episode title card might have looked.
