They were both good, but Lament did better at explaining how Dracula came to be and why, and why the Belmonts are sworn to hunt the night.
It also not only made an origins for the Belmonts, but for Vampire Killer as well. We see how it became Vampire killer, and why it is bound specifically to Belmont blood, leading to life energy drainage and premature death in anyone not of Belmont blood who tries to wield it at it's full power.
Lords of Shadow on the other hand, was more structured like a movie. And yet, this is not like MGS, where the game is big on cutscenes, but rather the gameplay itself feels like part of the movie as well. The camera helps with this by actually acting like a real camera. it gets wet with drops of rain or snow, and is NEVER still, when you stand there, jittering around slightly as if someone was holding it.
Gabriel as a Belmont works pretty well, he is reminiscent of Simon from CVll, (armor) and fits in with John Morris of being built like a truck.
However, they didnt explain properly in the game, WHY or HOW he becomes Dracula, only now going to add on to that with DLC which supposedly gives us insight, or the origins of the Combat cross, other than Rinaldo making it and it's enhancements, making the weapon more of a side element to the story, as opposed to the actual characters themselves. They leave it open to guess just how the future will play out, considering that a Belmont is Dracula.
Interesting note though, both Belmont clan founders- Leon in the IGA verse and Gabriel in the Cox verse, both loose their beloveds, spurring them to hunt down unholy creatures of the night.
I do live the combat cross though. pretty creative imagining of the classic Castlevania chain whip seen in the games.
speaking of which, I DO love that Gabriel sprite up there on the top banner.
