Wow, that is a pretty complex explanation as to why Americans dislike his voice acting lol. I doubt anyone thinks that deeply into it.
Almost every reasoning I have seen for not liking his voice boils down to his tone. They say he has flat, emotionless speech. If racial relations play into it, I've yet to see it.
Yeah, sorry I wasn't talking about his voice acting in isolation. I was talking about how relateable he is to American audiences - and speficically to those who enjoy dragon age games. He is often castigated as a stereotypical, generic character who lacks emotion when he can be shown to be anything but.
This is compounded by other unfortunate issues such as the misconception that Geralt is some kind of chauvinistic wandering womaniser when again, that simply isn't the case. The women in Geralts life dwarf him in terms of influence and individual power and use him far more than he can be said to use them. Hence, alot more import is given to this aspect of the witcher games than is required (the collectible cards...)
Lastly, Dragon Age fans have certain expectations regarding the treatment of social issues in their games. The witcher games have a different context and address these issues differently which I don't really want to get into now.
