This was one of the Super NES's earliest games, and helped kickstart Nintendo's bid to regain any ground they lost to the Sega Genesis - which got an earlier release - in the 16-bit wars. It's a great game, and my personal favorite in this series.
It isn't a sequel to the earlier games, nor is it a prequel like the third. This is nothing less than a remake of the original Castlevania starring Simon Belmont. That's right, we've gone from the original, to a sequel, to a prequel, to an original remake. It's pretty weird, but at least it's less confusing than Zelda.
Because this game is SO GOOD, I decided to do something special with this one rather than my usual spastic commentary and juvenile references. Thus, it will be narrated entirely by the protagonist, Simon Belmont.
Take it away, Simon.
