This isn't entirely on-topic, but as someone who's only played one castlevania game (I believe it was on gameboy advance? I don't even remember much about it), which games in the series are the best? On the highly unlikely circumstance where I find myself with time to play through some games I haven't gotten to yet it would be nice to try out some of the Castlevania ones.
It is kind of hard to say because to me the series kind of splits into two equally fun diverging paths.
One is VERY RPG and has merit. While the other is very action platform.
Pretty much this.
Pre Symphony of the Night, Castlevania was all about action-platforming without RPG elements. Beating the game with a high score, or just seeing the end is the goal. This covers most Castlevania games from Nintendo, to Gameboy, to Sega to the N64.
Starting with Symphony of the Night on the PSX, the series takes a more Action RPG (although still 2d side scrolling) approach. Levels aren't something you do once and then progress past, you're revisiting constantly as you explore different paths through the castle. The whole castle map is open and replayable. (Basically, think Super Metroid Style. It's where the "metroid-vania" label started.) After Symphony of the Night there's a string of Nintendo DS games and such that are a continuation of the same design, on a smaller scale.
Then you get into the next-gen Castlevania games, which are your bog-standard 3rd person action fighting games with some RPGness thrown in there, some exploration, but the major focus is on the combat system, the set pieces and the cinematics. This describes every Castlevania from Lament of Innocence to Curse of Darkness, all the way through to the last couple major Castlevania games (Lords of Shadow 1 & 2.) Pre-PC Castlevania games (so Lament of Innocence and Curse of Darkness) understand that players liked RPG features and each have their own quirks (In Curse of Darkness, you basically get demons to follow you around and level up them into several different evolutions), but the level designs fall really, really flat. Amazing how a 2d game with non-interactive backgrounds still manages to feel more fleshed out than 3d game spaces.
In PC-era Castlevania games, the level designs are a little better but there's none of the fun, quirky, enduring RPG stuff to it.
For me, Symphony of the Night era Castlevania games are the best. They're the best blend of flavor, music and design and playability. They're almost sandbox RPGs loaded with tons of equipment, secrets, enemies, bosses and secret endings. They've got that charming 90s JRPG aesthetic. They're games you can live 100 hours in easily.The older (NES to Sega) era Castlevania games have flavor and pretty rad music, but they're still basic, almost arcade-y games as befitting the time they were made. You're there to whip some dudes and get through a level, not live in the game. The newer Castlevania games, while they look good, the flavor feels like it's being borrowed, the themes retreaded and reimagined, the drama taking itself a little too seriously. (Basically castlevania trying to be adult versus previous game's almost....comical levels of drama.) Replace the charming 90s JRPG aesthetic with next-gen hotness. And like Nintendo-Sega era Castlevania games, going through the game is mostly a one-shot experience. There might be some oblgiatory retreading after you get X upgrade that lets you use Y path finally, a couple secrets to find, maybe New Game+....otherwise the games are a straight shot from start to finish.
In the end the Castlevania games are mostly about flavor to me. The music, the area designs, the boss monsters....Symphony of the Night does all those things well, and then drops an eminently enjoyable gamespace and systems on top of it. All the other Castlevania games, of any era, do not manage to hit all the notes like it does in my opinion. Symphony of the Night is also the only Castlevania game that, I dunno...actually
felt like you were in a castle. Each area more or less logically connects to the next, an idea taken from the earliest Castlevania games and exquisitely executed in SotN. As time has gone on in the series, that seems to have gotten less and less important, to the point half of "Lords of Shadow"
doesn't even take place in the Castle itself.Put another way, Symphony of the Night's level design is rad the way Dark Soul's level design is....and the Castlevania games following after have weaker level design, the same way Dark Souls 2's level design isn't as a good as Dark Souls 1.
Also, Bloodstained just hit $5 million.
