Doesn't have anything to do with being "Wapanese", or whatever.
When I watch a movie that was created by Germans, shot on German locations directed by a German director giving directions in German language to German actors speaking German then I goddamn want to listen to what those German actors have said in the language this movie was planned and executed in.
A translation is
always an abstraction on the original intent and I want this abstraction to be as small as possible. By watching a movie with subtitles I at least can grasp what the actors and the director intended by listening to their act, even though I don't understand the language they talk in. Expression of emotions is the same everywhere - I will get that. In a dubbed movie, on the other hand, not only the actual dialog gets translated and thus changed, but also the voices of actual actors, thus adding another level of abstraction. Not only the voices get replaced, but dialog in another language has to be fit to the movement of an actors lips, thus altering the original even more
Think of a translation of a movie or a game like a game of
telephone (or chinese whispers). First dialog gets translated -> then it gets changed to fit lip sync -> then a voice acting director adds thoughts -> and last, but not least a voice actor acts out his impression of the actual dialog. And on each iteration information gets lost.
By watching a movie with subtitles the only layer between me and the original movie is the translation of the subtitles and my reading skills. Not some stupid voice actor who may or may not be capable of speaking like the original actor or a director who has had nothing to do with the original movie and may or may not interpret scenes differently from the original director. Chance is that a dub will be very good, but there's chance that it will be a major disaster, too. Bad thing is, you won't know that it was the actual dub that was bad - you just see that you didn't like the movie. Subtitles can be bad, of course, too - but there's much less opportunity to fuck them up.
To get back to the original topic: it is the same with computer games that were created in a foreign language. If there is voice acting I want it in the language it was intended to be.
NOTE: I am German myself. If you are going to argue that I of course will understand German movies because it's my native language than you most likely haven't understood what I wanted to say (most likely due to my bad english skills). Please re-read this post, replace the word "German" with "French" this time and think about it again.
