You're getting deep into Japanese game development in Tecmo's Fighter Chronicle series for Dead or Alive 5. There are subtitles so you won't have to learn the language to understand what they guys are talking about. I will say, though, that focusing on a subject matter that interests you --like video games-- is a great way to learn another language. Watching soccer helped me learn Spanish more than reading about "Tato y Lola" running to the library every frickin' day.
Anyway, we're talking about DOA5, right? In this behind the scenes video you'll read and see that there's a whole world developing around this fighting game. And that's a good thing considering it's a franchise that's been around since the 1990s and nobody has cared until DOA5 to actually explain who these folks are and why they're fighting in a way that makes sense.
