I'm in the "nothing would have really changed" camp. Regardless of that game's success, the series would have still petered out after 3 or so games like it did in real life as Konami transitioned to a swiftly abandoned cash crab on mobile and instead tripling down on casinos and arcades -- they've made it pretty plain since even before the first Lords of Shadow that this was the direction their long-term plan was going to be headed in.
We would have gotten a 1-3 games of appreciable effort but probably middling quality and we'd be bitter over the fact that Castlevania fizzled out rather than imploding like it did in our reality thanks to LOS2. The Pachislot games would still be around to be reviled though, most likely.
I don't like it either, but the issue was never Lords of Shadow, or even Castlevania. The issue was rather changes going on at Konami, in personnel, attitude, and the rapid and unstable changes and disruptions in their key markets. It really seems like all the "what if" topics and Lords-blaming among the Castlevania fandom has started to reek of bitterness rather than actual curiosity of how things might have turned out. If that actually is the case, people really need to get the hell over it. If not, well then... I guess I apologize.
Castlevania sank and it sank deep. It sucks, but I can't even fully blame Konami for this. There's a LOT I
can blame them for, and rightly so, but this is not one of them. A lot of money was spent on the Lords of Shadow trilogy and when it ultimately failed to perform, well, there were going to be consequences for that sort of failure. But more than that, the wheels at Konami had already been turning away from console gaming for several years before Lords 2 made the coffin Castlevania is currently resting in. The failure of Lords 2 didn't
cause Castlevania's death; it just further demonstrated to Konami that moving away from console gaming was a smart choice and so they cut their losses sooner rather than later.
But no matter how many threads we make or how we might imagine a perfect "savior game" might have come forth like a heroic Hungarian (or is he Swedish?
) warlord to rally the people and save the franchise, that was never in the cards. The state things are in now is pretty much always how it was going to be after we crossed a certain point sometime after 2007. Castlevania was going to end up this way, Lords or no Lords. Lords just made it happen a few years sooner, and I'm not certain I'd have preferred otherwise.
At least this way Iga gets to make Bloodstained and we generally still like him. If his game had been made... I'm not sure that would have been the case.
Now whether Castlevania stays dead or makes like a Dark Lord and rises again? That's something only the future can tell.
