Lookin' pretty awesome. I'm liking the art style and the use of the Wii Remote. Unless I'm mistaken, in
this video, the Wii Remote is a shield and/or sword? I've just started playing Dragon Quest (VIII), so I'm intrigued by this. I'll probably get it, assuming it comes to PAL territories.
Regarding the official site for the game, I think the "SWORDS" musical effect is a nice touch. As for the new trailer, first thing that came to find was Kouichi Sugiyama's awesome music, which seems pretty strong as usual. The same goes for the graphics, however I think I prefer Dragon Quest VIII's cell-shaded style. (I'm a sucker for cell-shaded graphics)
Jam it back in, in the dark.
