4. Final Fantasy - 80 million
The Final Fantasy series of games inspire a level of devotion and following rarely seen. The complex world of each game and intricate story entice and enthral gamers time after time. The newest release in the series is often completely unrelated to previous game; this freshness and the level of characterisation in each edition are key parts of its enduring appeal.
It became such a cultural phenomenon that a feature film was released in 2001. 'Final Fantasy: The Spirits Within' featured the voices of Alec Baldwin and Ving Rhames but it still lost over $120 million at the box office.
