Chances are, if you're interested in playing Tecmo Koei's Fist of the North Star game, you aren't just tolerant of Japanese voices in video games, you prefer them. The company is aware of anime fans' preference for Japanese audio, and told Eurogamer that it will retain the original voice track in the North American and European releases of the Dynasty Warriors-alike. You'll be able to hear "ATATATATATATATATA" in the original Japanese.
In order to satisfy both the audience who craves authenticity and the audience who likes knowing what the characters are saying, Tecmo Koei is also including a full English voice track. That way, you won't have to have your screen filled with subtitles reading "ATATATATATATATATA."
