Okay so before we get into the portable stuff. I'll get the big one out of the way:
Castlevania: Symphony of the Night
Played on PS1/PSP/Xbox 360/PS4
I've played through this game so...SO many times. I have like one trophy left to get on PS4. I think I got all the achievements for 360.
I have an actual physical CD soundtrack for it. I just love the game. Even with its early series issues, I just don't have a problem with that. They are too minor to knock down the rating. I desperately want to get the Saturn version to play through the extra areas.
Rating None other than an S of course.
The Portable stuff:
Castlevania Adventure
Played on Gameboy/Super Gameboy
Never got too far in it. Never beat it. I want to. It's just a bit clunky being on the gameboy. Yeah they just didn't quite get it right. I wish SO BADLY that I could play the Rebirth version of this on the Wii, but I didn't manage to get it, and now my only option would be to buy a Wii with the game already on there. >_<
Rating TBD
Castlevania II: Belmont's Revenge
Played on Gameboy/Super Gameboy
I've heard it's better than the first one, and it does seem to have some quality-of-life tweaks, but again I've never actually played all the way through. I think I got farther in this one though.
Rating TBD
Castlevania Legends
Played on Gameboy/Super Gameboy
The only game we'll have get Sonia Belmont as this game's story has been declared noncanon. I know I've tried it out, but I couldn't tell you much about it.
As for another game with her though, you could always go find the dump of the unfinished Dreamcast game she stars in.
Rating TBD
Castlevania: Circle of the Moon
Played on - GBA SP/ DS
The card system was alright. I remember getting to an arena area and having problems. I did finally complete the map and then the game. It's not bad, but yeah not easy to see if you aren't playing the switch port, or have a GBA SP. (Or the GBA player for the Gamecube, which I do have) I honestly just don't recall much of this one, so it didn't stick.
Rating: C
Castlevania: Harmony of Dissonance
Played on - GBA SP/ DS
Honestly I like this one. I like the way you can use different spell effects like ice or fire to change how a sub weapon works. I only ever had one instance where I couldn't figure out where to go. It was bad that it was basically just one door I hadn't gone through, but after that it was fine. I even somewhat remember the story.
Rating B
Castlevania: Aria of Sorrow
Played on - GBA SP/ DS / Collection on Switch
And here we come to my favorite. I love Soma so much. I love the mechanic of gaining souls and getting abilities. It's a wonderful game.
Rating S
Castlevania: Dawn of Sorrow
Played on - DS with Aria in the GBA slot for the Mina doll and the Rare ring.
Better graphics, a neat synthesize system to put souls in weapons. It's only knock is the seal system. I need to get the Dominos collection to fix that.
Rating S-
Castlevania: Portrait of Ruin
Played on - DS
Weird story about this. I thought I lost it for a while only to find out it fell into a couch and I got it back like a year later. As for the actual game, it's been a while since I played it but I do know I enjoyed it.
Rating A
Castlevania: Order of Ecclesia
Played on - DS/3DS
So it's definitely a unique battle system, but I do think it's rather good. Played through the game once, but never beat it again because of one major issue.
An issue that is: "I'm an idiot, but I can't help myself."
So there is a thing in this game where if you beat a boss and never get hit once, it gives you a medal. I'm determined to get all the medals. Sadly on hard I can't get past
and on normal a shadow boss. Still it's a really good game.
Rating A+
Castlevania Lords of Shadow: - Mirror of Fate
Played on 3DS
Only played a chunk of it, but it's not bad. Solid B probably. Can't say too much yet as I never got around to beating it.
Rating TBD
That's it for the portable stuff!
