I touched on this idea in another thread, but as I genuinely think it would be a profitable venture for Konami, I thought I would take a moment to add some details to the whole thing.
The concept is simple -- in order to consolidate the classic games for long-time fans while allowing new players to catch up on the 26-year-old franchise, Konami should release a massive anthology of CV titles that would be easily emulated/ported on current consoles. A retail hardcopy release could be made for 3DS and Vita, while digital distribution on Steam, PSN, and XBL would bolster overall profitability. Because the included titles would largely be a few generations old, all of them could easily fit on an 8GB card, and only minor adjustments would need to be made on the 3D entries to port them properly. By my estimation, such a project would cost Konami less than $1 million even with production/distribution included, take between 3 to 6 months for development/testing, and would only need to sell 83,000 hardcopies or 41,000 digital copies (or a mix of 50k retail and 17k digital) in order to be profitable. From a business standpoint, that's as close to a sure-fire success as Konami could hope for, and while a $39.99 price point for retail ($34.99 for digital to incentivize downloads over the more limited hardcopy release) may seem low for a massive collection of classics, there's no way Konami could get that kind of money from individualized digital releases.
All that being said, these are the games/chapters I would include in such a so-called Classic Timeline Anthology:
(01) 1094 - Castlevania: Lament of Innocence
* This would just be a port of the PS2 version. 3DS and Vita should both be capable of handling the game with only minor tweaks.
(02) 1476 - Castlevania III: Dracula’s Curse
* The classic NES title, now with bilinear filtering.
(03) 1479 - Castlevania: Curse of Darkness
* As with LoI, this shouldn't be a huge problem to port from PS2.
(04) 1576 - Castlevania: The Adventure [ReBirth]
* WiiWare's ReBirth version could be used for its enhanced aesthetics over the old GameBoy release.
(05) 1591 - Castlevania II: Belmont’s Revenge
* No ReBirth version available, so this one would just be a GB port.
(06) 1600s - Castlevania: Order of Shadows
* As the only retail release of this chapter, many players could enjoy this mobile-exclusive CV for the first time.
(07) 1691 - Castlevania / Super Castlevania IV / Vampire Killer / Haunted Castle / Castlevania Chronicles
* Including the NES port would probably be enough, but as the central chapter of the CV saga, it might warrant packing in all five versions, especially since US players may not have had the opportunity to try VK or HC before.
(08) 1698 - Castlevania II: Simon’s Quest
* Again, this would just be the NES game refreshed with some clever filtering.
(09) 1748 - Castlevania: Harmony of Dissonance
* The GBA port in all its glory.
(10) 1792 - Castlevania: Rondo of Blood
* Since the Dracula X Chronicles are already available digitally, I think this should just be the original PC-Engine release, much like the unlockable version in DXC. Still, I suppose the SNES Dracula X or 2.5D PSP version would be fine alternatives if Konami preferred it that way.
(11) 1797 - Castlevania: Symphony of the Night
* Quite possibly the most re-released entry aside from the original, SotN never seems to get old. Maybe throwing in the Saturn edits would make it extra interesting this go-around.
(12) 1798 - Nocturne in the Moonlight
* Technically the same title as SotN, this is the radio drama sequel that has been released on CD in Japan. I think this could be presented in a visual novel style, with Japanese audio and English text, utilizing recycled SotN character portraits and other backdrop art. This would take some minimal assembly in development, along with some translation work, but ultimately, it would still be a quick production cycle since it wouldn't include any actual gameplay.
(13) 1800s - Castlevania: Order of Ecclesia
* This one is still pretty recent, so other than making adjustments to a few versions that don't have a dual-screen setup or touchscreen input, OoE could be included almost as-is.
(14) 1830 - Castlevania: Circle of the Moon
* Again, this is a simple GBA port.
(15) 1844 - Castlevania: Legacy of Darkness
* This one was a rarity on N64, so including it could allow players to see what they missed (or didn't, depending on your opinion of it). Either way, LoD wasn't highly demanding on a technical level, so only minor code changes would be necessary.
(16) 1852 - Castlevania 64
* Pretty much the same as LoD on a technical level, but much less rare. Love it or hate it, this would be a quintessential N64 port.
(17) 1897 - Dracula
* This could be an interactive ebook of sorts, with the ability to swipe between pages and bookmark your progress. But this wouldn't just be a straight-up copy of Bram Stoker's original. No, just as Pride and Prejudice and Zombies did before it, this would infuse the public domain work with new Castlevania-related details, including some clarity on Quincey Morris' relationship to the Belmont bloodline, the age discrepancy for his son John, and backstory changes that would fit better with the events of LoI. There would be no actual gameplay, but this could still be an especially cool fanservice inclusion.
(18) 1917 - Castlevania: Bloodlines
* Finally, a true fan favorite would be ported to more platforms than just Sega Genesis.
(19) 1944 - Castlevania: Portrait of Ruin
* Like OoE, it would require some tweaks to the interface for non-dual-screen formats, but PoR still feels pretty fresh by today's standards.
(20) 1997~1999 - The Demon Castle Wars
* As we've never had an actual game for this chapter, this would be Konami's chance to include a Prologue of sorts, using interactive visual novel sequences to tell the events of 1997-98 leading up to the final showdown with Dracula during the 1999 eclipse. This would be the first full resurrection since 1897, so the anthology's Prologue chapter could show how Julius, Alucard, and other involved parties got together before the eclipse. Then, Konami could plan a completely new, separate retail game called Castlevania: The Demon Castle Wars to continue the events shown in this timeline collection. This would also let the relatively inexpensive Classic Timeline Anthology build interest for the more pricey development of The Demon Castle Wars, with all of the potential fans being completely up to speed on the story before this critical new release. Perhaps the anthology's chapter could even end with the first teaser trailer for CV:DCW, thus driving anticipation (read: preorders) for both games.
(21) 2035 - Castlevania: Aria of Sorrow
* GBA port, of course.
(22) 2036 - Castlevania: Dawn of Sorrow
* Same as all the other DS ports. This is a personal favorite.
(23) 2037 - Ricordanza of the God Abyss
* Like the Dracula chapter, this could be a translated and transcribed ebook of sorts, mainly consisting of text and a bookmarking function. Encouraging gamers to read can be a good thing sometimes, right? Well, that's especially true when it's a Castlevania story that English players have never had access to.
(24) 11th Millennium - Castlevania: Judgment 3D
* Ah, this could be the one and only chapter optimized for 3DS's 3D capabilities. It's also more technically demanding than the others because it was a seventh-generation release, but at least it's only Wii that we're talking about here. Textures and polygon count would likely need to be reduced slightly, but otherwise, its arena structure and limited 3D environments mean that it wouldn't be terribly difficult. Fighting games have waned a bit lately, but they're still well-suited for handhelds, as they offer bite-sized gameplay sessions and a fair number of unlockables. Of course, having OoE in the same anthology would mean having Shanoa and Aeon unlocked just by playing that chapter first. Say what you will about Judgment; it still has enough fans' curiosity that including a fresh handheld version (or digital port) could be positive for the entire anthology.
(UNLOCKABLE / SEMI-CANON) 11797 - Akumajo Special: Boku Dracula-kun
* First official port of the Famicom classic outside of Japan. Technically, Galamoth and the 11th Millenium time frame are connected to the events of Judgment, and tangentially to the rest of the series. However, due to the comical presentation, few fans take the Kid Dracula games to be truly canonical. It would still be cool to have them as extras, though, as they were enjoyable CV games in their own right.
(UNLOCKABLE / SEMI-CANON) 11797 - Kid Dracula
* Sequel to Boku Dracula-kun, ported from GameBoy.
(UNLOCKABLE / NON-CANON) 1450 - Castlevania: Legends
* This GB title is one of the most debated entries in the CV franchise, and since its story basically suggests that the entire Belmont bloodline could have been human-vampire hybrids, Igarashi retconned it from the official timeline. However, because of Sonia's popularity, it has remained a highly sought-after collectible and a favorite among less discerning CV fans. The anthology may also make reference to the planned and cancelled Dreamcast title Castlevania: Resurrection (also starring Sonia), for which there is an abundance of concept art, screenshots, and even a handful of videos that are quite interesting, if nothing else.
(UNLOCKABLE / NON-CANON) N/A - Castlevania: The Medal
* Since this is essentially a series of video loops for Konami's Pachislot releases, they could be adapted to an unlockable Pachislot mini-game. This would also be the only way players could enjoy its content in a retail release.
(UNLOCKABLE / NON-CANON) N/A - Castlevania: Encore of the Night
* The iOS puzzle game EotN could also be adapted as an unlockable mini-game.
(UNLOCKABLE / NON-CANON) N/A - Castlevania: The Arcade ~Travel Guide~
* This would be an in-depth, interactive guide to the recent arcade game, which could likely be ported to the Wii U (or maybe Kinect) in the near future. Including such a guide would potentially tease the release of a console port, spurring profitability for the franchise's later titles and encouraginf fans to embrace their... unique take on Castlevania.
...
Additional content for the Classic Timeline Anthology may include a music player, a gallery of Ayami Kojima artwork (and others), interactive character models, a beastiary, and of course a visual timeline to show character connections, resurrection cycles/resets, and other story nuances. I toyed with the idea of including Harmony of Despair's multiplayer features or a Castle Editor for shareable user-generated challenges, but that might be asking too much. Even my aforementioned UNLOCKABLEs might be unnecessary. Frankly, I would just be happy to see all of the primary games included in a single collection, even without the bonus stuff.
But if it were up to me, this is the format that such an anthology would follow. How do you feel about it? Have I missed something critical? Do you think Konami's missing the boat by not putting out an anthology? Or do you think they might actually do something like this in the not-so-distant future?
