Star Wars Legends is often debated by Star Wars fans. Some fans love it, as they grew up with it and spent years reading the books and comics, as well as playing the games, of the video, tabletop, role-playing, and card varieties. For Sequel Trilogy fans, Legends is roundly criticized, as many Legends fans say the stories they like are better. Legends may have been rather complicated and its canon status was subject to change, but it created some amazing characters and stories that inflamed the imagination of fans and kept Star Wars alive during the dark years from Return Of The Jedi to the release of Special Editions and the Prequel Trilogy.
