Beat the main game and DLC after 36 hours! Ended up at level 89 using mainly Ludwig's Holy Blade +10.
I'm a big fan of Demon's Souls, Dark Souls, and Dark Souls III, and have wanted to play Bloodborne since the day it released. I only recently got a PS4 Pro and of course Bloodborne was the first game I purchased.
I am not disappointed. The gameplay in this series is as fantastic as ever here, with some really cool and welcome nuances. The atmosphere and soundtrack are fantastic, the art is breathtaking at times, and the bosses on the whole are pretty goddamn strong (especially the DLC). Overall, I'm not quite sure where this ranks among my favorites in the series, because they're all good in their own ways, but I can definitely see why it's appealing to so many people.
Just to finish up the list, here were the most difficult bosses, in my opinion:
1. Ludwig the Accursed
2. Orphan of Kos
3. Blood-Starved Beast
4. Laurence, the first Vicar
5. Shadow of Yharnam
7. Lady Maria of the Astral Clocktower
6. Martyr Logarius
8. Cleric Beast
9. Ebriates, Daughter of the Cosmos
10. The One Reborn
11. Darkbeast Paarl
12. Gehrman, the First Hunter
13. Vigar Amelia
14. Rom, the Vacuous Spider
15. Amygdala
16. Moon Presence
17. Micolash, Host of the Nightmare
18. Mergo's Wet Nurse
19. Father Gascoigne
20. The Witch of Hemwick
21. Living Failures
22. Celestial Emissary
Ludwig is the hardest boss I've fought in the entire series (all solo). Nameless King, Ornstein & Smough, Flamelurker... none of these have given me as much trouble. Hell, I even beat Orphan of Kos in only a few tries. But he felt beatable from the first attempt. Ludwig didn't feel beatable to me until attempt 20 or 25. LOL But my goodness, he may exemplify the Souls series better than anyone: aggressive, relentless, tragic, beautiful, grotesque, insane... Perfect conglomeration of every Souls series motif.
With that, my favorite bosses in the game:
Ludwig, Orphan of Kos, Martyr Logarius, Lady Maria, Ebriates, Gehrman, Vigar Amelia, Father Gascoigne... Really strong collection there.
Only thing I didn't really do were the chalice dungeons. Played a few levels of the first one but could see how they sour the game for so many people with their repetitive design, so I stayed away.
