Tolkien, but also because of Peter Jackson's phenomenal film adaptation, which won 17 Oscars and still holds the record for the highest-grossing film of all time. As for video game adaptations, they experimented with different genres: from online MMO-RPGs to strategies with varying levels of quality. Most of the games came out after the films and have since become technically and morally obsolete.
