In part three of the Nerd's retrospect, he talks about Super Castlevania IV, Castlevania: Dracula X, and Castlevania on N64. After watching this, I want to go back and beat Super Castlevania IV. I have it on my Wii but, never beat it. Parts 1 and 2 can be located here (1) and here (2).
Yea I watched it up on Game Trailers. Early on he says he had 'no idea it could actually get better', well I thought things would keep getting better and better and better... I too got the first Castlevania on 64 and I think I got stuck at the same part. God that game was shit.
More than even the graphics, Super Castlevania IV was a demonstration at how amazing SNES's music could be.
