even if it fell flat.
I'm sure Maria'd prefer it
bounce instead of fall
flat.
If you get my hint.
I suppose you could say it was a rather
big hint rather than a
small one.
Wow,
both of those were quite the
prominent hints, weren't they?
*waits*
An entire story mode wasted on a little girl (previously shown to have been strong, determined, resourceful, and tough-as-nails if still playful) fixating on everyone's boob sizes isn't a broad strokes characterization?
There's tons of other stuff in there too, but since we're mostly talking about Maria here, her Judgment personality in general fails to resemble canon Maria in any way that really matters.
And PlotTwist, I don't hold it as noncanon because it's a bad game (it's actually pretty okay), I hold it as noncanon because the very nature of the time rift holds events in an unstable state, and so anything that transpires within is wiped out as the rift vanishes. In more direct language, any meetings between say, Trevor and Alucard would go unremembered by either party, because they only occurred whilst the rift enabled it. Judgment is canon
while the events within are happening, but snaps back to a noncanon state as soon as the plot is resolved, because otherwise we wind up with nasty details like characters having foreknowledge of future events (if broadly). Any changes made to the timeline (by the mere convergence of timestreams and future people meeting past people) would by definition HAVE to be wiped out or history as a whole is messed up afterwards. The sheer potential for history-breaking time paradoxes is simply overwhelming.
Hence, Judgment exists in a separate timeline by its very nature because it must, regardless of Konami (or IGA's) official word on the matter.
More on topic, the minutia of Rondo of Blood aren't that important to canon, per say.
I would hold that the way Symphony portrays the ending is the most important aspect, and my interpretation and headcanon for Rondo is as follows:
Richter saves Maria, and tells her to go home. Maria refuses, and insists they work together. Richter won't have Maria in danger, so he... tells her to go home again (because he's a vampire slayer, not a dad). Maria pretends to, and doubles back more or less immediately as soon as Richter moves on.
From here, whichever path the player has Richter take is the canon one (but it can be reasonably inferred that he saved all the hostages, and almost out and out guaranteed he saved Annette at the very least).
Maria's gameplay mode is her journey to catch up to and help Richter (the ending to her mode is non-canon).
As for the ending, during the battle against Dracula's Final Form, Richter rather cocks up and underestimates Dracula's power. However, just as he is on the edge of defeat (illustrated in SOTN's prologue by getting your butt whooped by Dracula), Maria bursts in and uses her magic to give Richter his second wind, allowing him to beat Dracula.
Castle crumbles, Richter gets bodyjacked by Shaft a few years later.
Aaaaaaaaand
Fin.
Everything fits and is relatively accounted for, even if a few niggling details like Dracula's third form from Chronicles fall through the cracks-- they can still be plausibly worked in as they are small details.
