As much as I doubt they'd make the no feeding ending that hard to get, I kind of hope they do. I doubt the protagonist, being a predefined one, will be anything you want him to be. So if there's an option to not feed that directly impacts the ending, the protagonist will most likely not want to feed, but act, in the story, as if he felt the need to. So I'm really hoping they'll make the player feel the same way.
Make that shit HARD.
Of course, the combat must be good enough for it to feel like a challenge too, not just frustrating.
We'll see, I'm definitely very excited for this one. I should play Remember Me before it comes out.
Focus Home is killing it with Vampyr and Call of Cthulhu.
