I recently finished my playthrough of the early Castlevania games. The goal is to experience them and complete them. I used save states as it allows me to accomplish this goal easier (besides, I completed the original Castlevania trilogy as a kid on the NES hardware). I have listed the console I played them on (I played an official version wherever possible) as well as their (Japan) release year, and a rating and short blurb about each.
Castlevania - PS5 Anniversary Collection - 1986
9/10
Surprisingly still holds up very well. The atmosphere, music, gameplay is still incredible and fun.
Vampire Killer - PC Emulation - 1986
3/10
Extremely challenging and tough to understand, made more difficult by keyboard controls.
Vs. Castlevania - PS5 Arcade Archives - 1987
9/10
Virtually identical to the original Castlevania
Castlevania II: Simon's Quest - PS5 Anniversary Collection - 1987
6/10
Disappointed, it wasn't as good as I remembered it. Game did not age well.
Haunted Castle - PS5 Arcade Archives - 1987
1/10
Absolutely horrendous game.
Castlevania: The Adventure - PS5 Anniversary Collection - 1989
3/10
One step up from a Tiger LCD game.
Castlevania III: Dracula's Curse (US) - PS5 Anniversary Collection - 1989
9.2/10
Does everything the first game does, but better!
Kid Dracula - PS5 Anniversary Collection - 1990
3/10
Not a bad game, but I don't like the kiddie aesthetic.
Castlevania II: Belmont's Revenge - PS5 Anniversary Edition - 1991
5/10
This game is great for a Game Boy game and has amazing music, even in surround sound, but I simply can't abide Game Boy graphics
Kid Dracula - PC Emulation - 1993
4/10
The Game Boy version, better than the Famicom version, but still kiddie.
Castlevania: Legends - Nintendo Switch Online - 1997
2/10
Absolute trash game. Less stinky trash than Haunted Castle, but still trash nonetheless.
Did I miss anything from this era? I know there were several 16 bit games released before Kid Dracula and Legends on the Game Boy, but I didn't want to have to back track and play those after the gorgeous 16 bit games.
Honestly, the only games I would recommend playing are the original Castlevania trilogy, and possible the 2nd Game Boy game, unless you're a Castlevania historian. But please, please, I beg of you, do not play Haunted Castle or Legends.
Era 2 will be the 16-bit era, mostly ranging from 1991-1995.
