While technically a text adventure rather than a graphic adventure, it was written by Douglas Adams and it is this writing pedigree that got this game on my list.
In this department, the game doesn’t disappoint. The humour and characters set the bar high very early on for what adventure games could provide in terms of narrative and experience, foregoing the fantasy and science fiction to present a biting satirical critique on the modern world, one that still feels fresh and relevant today.
