Mostly are from the 80s. I only included the animes I have watched from these years. I'm not including Sequels from anime that started on previous years. I am including Sequels where it makes sense to keep watching, in order to complete the story.
Excellent anime for developing fans, shows were chosen for their quality all around or as a standout example of a given genre, for example Cardcaptor Sakura for mahou shoujo, Higurashi for Horror/Mystery, Yuu Yuu Hakusho for shonen, etc.
