A looooooong time ago, I used to imagine that characters like Christopher and Trevor were Simon Belmont, because I thought a Castlevania game without Simon was just un-cool! I would conjure up stories in my head as to why Simon was fighting Dracula again.
Of a similar note, I used to own that one classic Gamefan (I think it was Gamefan) magazine that features Symphony of the Night and has Alucard on the cover. I thought that Alucard was supposed to be Simon Belmont, and I was like "WTF is this!?"
I grew up with Simon Belmont as an one of my iconic game characters, like Link, Samus, and Mario, so, you know... not including him in Castlevania was retarded to me. When I read up on Harmony of Dissonance, it made a specific connection to Simon Belmont by stating that Juste is Simon's grandson, and when I found out it referenced Simon's Quest a lot, I was spazzing out with excitement, so I was like, "Okay, I can play into this. This is stuff I know!!!" Before that, there was Circle of the Moon talking about some Quincey Baldwin or some such, and I was like, "...who the fuck!? Can we just get Simon? What the hell?"
Most people probably think I'm one of them Symphony of the Night starter dudes, but nah, I'm OG. I just kinda' keep it under wraps.
I'm so OG that I wouldn't even accept a game that didn't have Simon : D
