Castelvania Chronicles just wasn't that good though, but I had played the original game before that and didn't care for it. Castlevania 4 was indeed a remake of sorts, but if they did remake it, maybe in the 2.5D set up that would be awesome, and the room tilt section would be awesome. The Rondo rerelease was way too long in the making though, and if they had done that years back instead of giving us a shitted up port for SNES with gimped up music and stuff cut out, maybe they would have sold the shit out of it.
But yeah, 1-3 needs to be redone hard. Especially 2. I love 2 to death.
