Players assume the role of Roy, and the goal of the game is to guide Roy through life, from childhood to death, overcoming obstacles along the way. The game's programming will adjust Roy's life path and the events that happen to him according to the decisions the player makes.
There is no point system in the game as the final score for the player is how many years Roy lived. To the unprepared players though, the game can be disorientating, as the memories players gain from the game will conflict with the ones from real life.
There was a sequel made to the game called "Roy 2: Dave", as well as a bootleg version called "Troy: A Life Lived".
