One very picky detail I have about the storyline translation is that I want to keep the dialogue as anime-perfect (or manga perfect) as possible. That way, Narutards can't be like OMG WTF WHYD YOU CHANGE THE DIALOGUE, YAMATO IS NOTHING LIKE THAT!!!
So - what I encourage, is that if you don't know Japanese; if you read the manga or anime, try to link to videos of where these fights occur in the anime, or simply tell me what chapters they occur in the manga. I can read both Hiragana and Katakana, so more often than not I myself will be able to match up the anime dialogue with the ingame cutscene. The manga's a different story but I'll manage.
If you wanna Youtube the big fights (and I don't care if dumb Linkin Park music is playing) and post them here, that'd be very helpful - oh, said scenes I need:
Hidan and Kakuzu chasing down the two-tailed beast, confrontation with Yugito
Asuma & Shikamaru vs. Hidan & Kakuzu
That scene where Asuma makes a dumb anime face
Whenever Akatsuki meets (esp. with Tobi and Deidara)
Naruto vs. Kakuzu
I don't remember all the fights but yeah any others, do link to Youtube or list the chapters which they appear in. Feel free to make a list of events that occur in this game [use spoiler tags though]
-After this though, I'll have someone like Rosales brush up the text, maybe give the characters some more personality and also translate the narration. And then you'll have a chapter.
