As a longtime fan of Dark Souls 1&2, i was excited about this. However since i do not own a PS4, i was not going to buy a new console before it was released, in order to have all the info i need to decide if i will spend so much in order to play basicaly one game. Now, i think i will pass due to various reasons:
1) This was known from day 1, but still it was one of the things i disliked. It seems to me like Miyazaki and his team lack creativity. It is the fourth game, spreading over 3 franchises(demon's souls, dark souls, bloodborne), where the games are practically identical. You have a curse upon you, no saves but checkpoints. Enemies respawn on death. You loose XP upon death and you regain it at the point of death. Combat is also almost identical on all games.
2) That was a big downer for me. The game has moved into being even more action and less RPG than previous titles. THe thing about Dark Souls was that despite being very much about player skill, and had a very complex combat system, it also had very deep RPG elements as well. On bloodborne, you have far less weapons and equiopment, far less varied movesets, only ONE playstyle -melee with no shield, fewer stats to raise while leveling and no big variation of armours. No magic builds, no ranged builds, no tanks. Strategy on fighting monsters also seems to be only on the action side of things, like big enemy -> try to stun him with your pistol since he is slow etc. Dark Souls had this as well, but you could build your strategy upon RPG aspects as well. EG. if you had problems with Darklurker you could tweak your character to push magic resists really high. Also the one thing disliked about Dark Souls, was that leveling was abit boring, cause you could only raise stats, and it had no skill tree. I mean it is more interesting to unlock a skill of a cool new move, rather than raising strength by 1. Bloodborne fails to improve upon this as well. It seems like FROM soft took one playstyle and focused on making this as good as possible, which can be a good thing for action fans, but not RPG fans who liked variations.
3) Very hack 'n slash gameplay. It encourages spamming, rather than patience and taking it slow like dark souls. This is not nesceserily bad, but i disliked spammers on DS. I have to play it to really see if this is good or bad.
4) Severe technical issues. Frame rates locked to 30 was already a big downer, but recent framerate tests also reveal big frame rate drops as well. Huge loading times, sometimes excceding 40 seconds. No beast form available yet.
