I think it could be really interesting, especially considering that CV is more popular over here than it is in Japan. The creators would be closer to and possibly be PART OF the existing fanbase making it a lot easier for us to get heard.
Absolutely. The fan base here has had a lot of issues with plenty of the past games (maybe not so much Ecclesia, we'll see how that pans out) but all of them fall on deaf ears because, hey, they're Japanese, they can't read our complaints.
For example, with Contra, they recognized that most American gamers were familiar with the two NES titles, and vaguely with the SNES game, but not so much the later titles, which veered in different directions. So, Contra 4 was much closer to the originals. That isn't EXACTLY the direction Castlevania needs to take, but it couldn't hurt to shake things up a bit.
