I have spent hundreds of hours on Dark Souls series. I wanted this iteration to diverge from the tried and true formula as a new ip. From what i've seen you could've told me this was Dark Souls or Dark Souls DLC and I would've believed you. You can only play the same hack and slash model for so long.
You'll be glad to hear, then, that Bloodborne deviates quite a bit from its predecessors in terms of gameplay. You will die a lot in the beginning, because you'll need to get accustomed to its new gameplay style.
