Well niichan-bro, I guess that you don't have a problem with a game being difficult as long as it gives you a good story right? That's the reason why I disagree with the majority of my friends when we discuss video games ... I LOVE difficult challenges and I think that the most entertaining aspect of video games is that feeling you get after clearing a very challenging situation ^^ man... Dark Souls satisfied my hunger for challenges. Especially after I started performing challenges and shit, like fighting bosses with no pots or without armor

I did that alot in the old days... (I'm planning to finish black ops 2 while using the handgun in all stages when I get it :S).
About making choices ... Dishonored had this too but in a completely different way. You choose to either kill or spare your enemies. You can use a non-lethal approach when clearing missions and they always remind you that the more people you kill, the darker the ending was.
You can easily tell the ending I got ... It was so dark it didn't show up on the screen

I killed every last NPC even civilians
