Comedian, voice actor, and television producer Seth Green isn't just the star of Nintendo's Dragon Quest IX commercial, he's also a client, or at least well-coached on the game's merits, as demonstrated in this video clip.

We posted the commercial yesterday, and I have to agree with McWhertor here - it really works. Green is truly believable as a RPG gamer, and despite being 36-years-old, doesn't come off as creepy hanging around with high school girls.

I would have been arrested in seconds flat.

Now Nintendo passes us this behind-the-scenes video, showing us that Seth knows Dragon Quest IX and isn't afraid to show it. It's likely coached, but the man sure speaks eloquently about gaming, doesn't he?
