Realm (1987)

From the inlay: From deep inside the Solar Control Centre, an ominous rumble signals the demise of the Planetary Orbiting Co-Ordinator. Consequently the Solar System is in a complete mess with planets all over the place. You are required to take charge of the remote control droid XR3, enter the Inner Co-Ordination Sanctum and reconstruct the Solar System. The object of Realm is to explore the maze, overcoming obstructions and solving problems, in a search for the nine Solar Planets. Once a planet has been located it will need to be correctly positioned around the Sun. Credits: By Paul Johnson
