You haven't played the entire game to see how the story plays out, you've just seen the ending taken out of context.When NT goes on and literally brags about how "deep" the story in DmC is supposed to be, I expect a pretty damn good ending to finish of this "epic" tale. But no, nothing of sort happened. It was a cliche and lame ending.
I'm not gonna say the story is good or bad because I haven't played the full game yet either, but I just don't understand how you are going to declare the ending lower quality after seeing a ****ty quality video where you can barely see or hear what's going on. Don't you think that's an unfair judgement?
