How do the 64 games take place in a time Rondo said Dracula was inactive when they take place after Rondo?
This is not what I said. I said the contradiction is "Dracula somehow existing in a time Rondo said he didn't", and this refers to Dracula's recovering his memories from 100 years ago, when he shouldn't have "memories" of anything to regain.
And remember Rondo and many of the other games were never given an exact year where they took place until SoTN was made, which was during the production of 64, so the whole "100 years I've been dead" or whatever doesn't really mean anything
I don't know where you're getting your info (please do share, this is strangely specific for you to be making up and I want to know about this), but CV64 was
10% finished by September, END of 1997, and
20% by February 1998, long after SotN had already released (March 1997). Development of SotN started
around three years prior to its release, so consider that.
Beyond that, SotN had Toru Hagihara as its director. Toru Hagihara is the man behind Rondo of Blood. So this does say
quite a bit about the choice of year for Rondo made in SotN, it wasn't just IGA making up numbers for his timeline. He had the mind of the person responsible for Rondo to guide him. And, yes I know SotN started as a gaiden game -- still holds up when it was completed while CV64 wasn't even at 10%.
Finally, things mean much more after they are complete than while they are in development. The two arguments above are meant only if you want to insist. So the CV64 "100 years thing or whatever" does mean a lot. It's basically the thing that sets up the problem at hand. If SotN -- released long before CV64 was at little over 10% -- said Rondo happens in 1792, then CV64 contradicts that very hard. If it was RELEASED contradicting something that was already out for two years, then it hints at an intention to "contradict it anyway".
That is not getting to Simon's Quest tombstone, the century given in CV3, the "over a hundred years prior to Simon" reference. You don't need to HAVE a timeline in your hand to know how the one we have was assembled and how they arrived at that year for Rondo. But this is besides the point, of course.
EDIT: Nagumo added something after me that I'd like to respond to. There is a discussion about "was it considered canon or not and did this status change or not with LoD". As I said before, this is the muddy part that I concur needs more research, but that source is not the first time IGA says that, and while he did put emphasis on LoD in the source I used, the
other time he made this statement in Japanese he included CV64 in the bundle. It does not seem to be an offhand remark to me (although yes, this bit of CV history is not as clear as I'd like it to be).
EDIT 2: And we now know there was a timeline YEARS before SotN, by the Bloodlines team, that already contradicted 64.
