If you consider that every Castlevania game after 2001 is Spin-Off to the series, nobody will try to create this strange game 1999, simply because it's just a story created by Iga and existing in Iga's spirit. Some fans would like to have this story, but for many other...who care ? Fighting the Chaos in 2035 in a eclipse with a pale white haired japanese student who has a knife on him when he studies, is that really a good storyline ?
For the next Castlevania :
A simple story with Belmonts or Other Vampire Hunters VS Dracula and Evil forces --> that's all I want.
We had this storyline for Bloodlines, Castlevania, Chi no Rondo, The Adventure, Circle of the Moon... and they are all great games !
