I just got to Chapter 10. I was planning on finishing the game before commenting, but...
1. Lords of Shadow is only reminiscent of God of War and Shadow of the Colossus if you're strictly watching. You absolutely cannot get away with button mashing in Castlevania and dodging requires far more strategy than God of War. This is especially true since health fountains aren't terribly common. Sure, light magic regains health, but the game forces you to earn health back. The Titans are mini-bosses and are played as such whereas the Colossi are the entire point of SotC and are significantly more intricate and difficult. So, it's reminiscent, but no where near the same thing. I think comparisons are unfair.
2. I've read a lot of reviews bitching about how Lords of Shadow is too much of a departure to even be considered a true Castlevania game. As a reboot, it has to. Lords of Shadow deviates enough to justify rebooting the entire franchise, but there is more than enough Castlevania in here to justify its namesake. The game devotes the most chapters/levels to the vampires. One way Mercury Steam could have made the game feel more like Castlevania is with...
3. The music. The soundtrack is great, but I'd be lying if I said I didn't miss some of the classic tunes. I was hoping for some remixes and I only notice one in...
4. The Musicbox level. What the Christ? Sometimes I feel like every game has at least one section that makes you want to just punch a baby in the face. God of war had the Hades level, Lords of Shadow has this nonsense. Thankfully, it was pretty short.
5. I love the plot so far. It's interesting even if the whole "avenge my wife" bit is old. My biggest issue is that you see so little of the Lords of Shadow. You don't see them until right before you fight them. They're interesting characters, but they're relegated to exposition cutscene then cool boss fight. Carmilla was especially interesting and the voice actor deserves all the credit in the world for that amazing performance.
6. The voice work in this game is some of the best in any videogame. So far, Patrick Stewart turned in the worst performance, if only for the melodrama. Worst, but still not even bad.
7. One save file? What the F, man?
8. I wish Gabriel wasn't so brooding. He's literally in Cloud Strife territory. That bad. Still, I think I prefer it to Kratos' excessive anger.
