To make this clear, for the first set on the list, NES castlevania is a port of the MSX version, Super castle vania, I i think is a Remake of the NES or MSX version, and Castlevania Chronicles is a Remake of the MSX version.
The second one, If you buy the Castlevania dracula x chronicles, Symphony of the night and Rondo of blood is included in the game as well, That game core is basially a remake of the Rondo of blood. and the saturn port of Symphony of the night.
I would recommend skipping the snes Dracula x game, if you plan on playing rondo of blood, is a inferior port of that game from Turbo Duo, to SNES But you can try if you want, for curious reaons, that game is hard and unfair.
If you want my experience you would play the 3 nes castle vania games, then gameboy ones the snes games then the one genesis game playstation ones, then GBA then ps2 (most people would skip this system) then NDS (There is 2 on the wii, castle vania rebitrh is a remake of the Gameboy games, and Castlevania judgement is a 3D fighting game) And then the ps3/Xbox60 of Castlevania judgement. Made by Hideo Kojima (Metal gear series creator)
I recommend skipping the N64 games, Castlevania 2 simons quest. "It is bad" Snes Dracula x, ps2 games, and the wii game is debatable. Is not a traditional castlevania game nor does it have any actual plot in the time line, is basically a allstar fighting game. Also the Ps3 and xbox 360 has one called harmony of dispair which looks like a mmo version of the NDS games
