Hey, just because I complain about those nice little "introduced midway in the saga" items doesn't mean I dislike them. Vanitas = Badass. X-Blade...well I didn't like the concept of it even while playing...And Unversed were filler if you think about how they were only created by Vanitas, but it is obviously hinting at a similar enemy that will appear in the future.
I don't deny that these things will be used, but seriously, he didn't need to add any of those plot points in. It just bothered me that this was introduced midway in the plot without any hints of it prior to BBS (or Days). BBS was the game Nomura advertised to fans as the game to fill plotholes that already existed. In the end it made more of them, and now it appear we'll have BBSv2 which will most likely be the true plothole filler.
I don't mind any of that, though. I just want Nomura to employ proper storytelling skills and plan these things before hand rather than throwing things in as he thinks of it.
Because that is exactly what he is doing.
