As much as I would like a 1999 game being made, I'm sure one won't be made. At least not for the old timeline. Who knows, if there is another reboot and it is more faithful to the lore of the old cannon than LoS was, we might get something like the unmade 1999 game. You know. A CV game where Dracula is defeated once and for all (unlike in the LoS saga….ha ha ha).
Yeah, the 1999 game we were all speculating about won't happen.
One final thing, if IGA had made the game, the story would likely have clashed with some of the established story like omitting the fact that the castle is supposed to be sealed in a solar eclipse, the fact that a priest from Japan is apart of said ritual, the fact that Julius seals the whip somewhere in the castle, and he might even forget that there is suppose to be a solar eclipse happening. It would be classic IGA. Gameplay and gimmicks first. Story second not caring how it fits into the overall story of the timeline.
