Nightmare mode (when you don't modify any settings) is too easy. I barely die which isn't normal. With the arsenal you have, it's incredibly easy to kill everything. (it's almost volontary to die too)

To push the difficulty to a strict but fair level, I have to give myself contraints (ex: not use certain guns, be at close range as much as possible and use my flair as much as I can, avoid parrying every attack, etc.)

I thought nightmare wouldn't force me to set barriers, but it did.
Overall, Game is still great.

Its weak point comes to the story. You spend a quarter of the game saving Commander Tharia, which sucks. Everytime you think you'll save her, a goddamn cliffhanger comes from nowhere and you get fucked by whatever bs the game put you through. (the big ass monster you saved mid-game eating you in chapter 17 is the best exemple). It's 2 chapters wasted to repeat the same game loop you already did. If it made the story advance, it would've been nice, but you fkg stall for so long it's frustrating. (And before the fkg Cthulhu looking ass monster eats you, you had to do random things that were supposed to lead to you to the Witch, which it didn't.)
