The best voice acting in a video game would be Daniel from Amnesia.
First of all he sounds like he's British. (which really fits the scene for me)
And the second thing is he puts a lot of emotion into his dialoge, and it's makes me really feel his emotions.
(I'm actually not quite sure if he's British, I mean I looked it up so I wouldn't have to straight up lie to you guys. But not a lot of information was shown for him, other than date of birth. The weird thing is that they didn't show place of birth. If any of you guys know if he's British comment or inbox me, it would be much appreciated.)
