Movie to video game adaptations of the early 1980s were difficult things. Raiders of the Lost Ark, E.T. the Extra Terrestrial, and The Empire Strikes Back were as hard to master as they were hard to genuinely enjoy.
And say what you will of Ubisoft's James Cameron's Avatar: The Game, at least it was no Avatari, John Earle's amusing but too short riff on the 8-bit possibilities of a mega-blockbuster whittled down to 4K. Designed for Australian TV show Hamish & Andy, there are some substantial spoilers in this very clearly rushed to market video game that never was.
