While many publishers often don't have second thoughts about flooding the market with annual revisions of their most commercially viable franchise, not every publisher takes that path. Some games are forgotten and their legacy, however big or small, neglected and swept under the metaphorical rug.
However, some fans are persistent and vocal enough to bring old IPs -- or even whole series -- back to life; Shenmue I & II HD serves as an excellent example of such dedication. Other, less fortunate titles are forever ignored, without merely a hint of a potential resurrection.
These unfortunate outcasts are mostly kept alive by loyal fans who express their appreciation of a particular video game or franchise via cosplay, music, and original artworks, for example.
There is a valid argument to be made that some stories should remain singular; developing a sequel would just complicate things. However, if certain titles receive the privilege of being released annually, then even a one-off follow-up to any of these entries wouldn't hurt, especially given their prolonged absence.
This compilation is comprised of games which have to date had only one official main entry and not released for at least five years.
