Alright, time to finally post my final thoughts on this series;
I have a big love/hate relationship with the LoS series. I still don't see LoS1 as a Castlevania game, but it's a damn good action game. If it weren't for Mirror of Fate I probably wouldn't have been so excited for LoS2 because of the inclusion of the old storyline everyone wanted in the first place; Belmonts vs Dracula.
Before LoS even came out I remember all of the incredibly misleading trailers that released making everyone think LoS1 would be Super Castlevania IV in 3D because that game was apparently their "bible" while developing LoS1, and have the traditional Belmont vs Dracula storyline. What made it so exciting though was seeing the series receive a larger budget treatment for once. I still remember the scene with Jason Isaac's talking while the camera panned around Dracula's Castle, which never showed up in the final game. It was a clip from their prototype with Simon Belmont to help pitch the LoS series. Horribly misleading, I remember being so disappointed when it was Carmilla I ended up fighting instead of Dracula. They even included that familiar staircase leading up to the throne room.
In the end the only things LoS1 did that reminded me of SCIV was the moody atmosphere, the whip swinging, and the occasional heavy rearrangements of songs from IV. I was never a fan of how many QTE's it had and how gory some of the deaths were. Not to mention, of course, the glaring similarities it had to God of War. I don't care how much MS will defend the GoW complaints, there were too many things ripped from it down to Gabriel's basic combat animations, balancing on planks of wood, and the health fonts. GoW was their primary influence instead of Super Castlevania IV.
I liked Mirror of Fate for what it was because I expected it to be LoS in 2D, and that's exactly what we got. It has my favorite incarnations of Simon, Trevor, Alucard, and Dracula to date. The character and monster designs are really fantastic, and a welcome shift from how Tolkien inspired LoS1's bestiary was. Not to mention it finally made the series seem like it was about the Belmonts vs Dracula, and not Belmont-Dracula vs Satan.
LoS2 looks like a huge improvement from LoS1 and hopefully one day I'd like to play it. In the end, Mercury Steam did what they hoped to accomplish, so I applaud them for that. As a Castlevania fan, I just want to see Konami leave LoS behind and move onto something new. I'm pretty sure MS wanted the same thing if they had plans to make the original ending to LoS2 incredibly tragic and bittersweet. I can only hope now Konami returns to 2D Castlevania, or creates a reboot that encompasses our original desires for the LoS series before we knew much about it.
...just keep Satan the fuck out of it.
If this comes off as negative, I was going for something more in-between. I enjoyed the ride over the years, but I don't want to see the LoS series become the new face of the franchise. I fell in love with Castlevania because of the gameplay of the 2D games, mainly the ClassicVanias.
LoS's heavy focus on hack and slash and borrowing ideas from other franchises has very little to do with that.
