*yawn*
Whatever. The only way that series is going to sell well over here is if Square-Enix stops using its 20-year old design document from Dragon Quest 1 for every game in the (main) damn series. And if they did that the series wouldn't sell well in Japan, so that's just not going to happen. A shame, really...I could really dig a DQ RPG that expanded on the concept of Dragon Quest Swords. But no, it'll be the same damn game as the 9 other games in the series that came before it, with slight graphical tweaks.
Nintendo can promote that game all it wants here, throw up all the commercials they want of "casual" players fiddling with the thing...but if the game itself isn't significantly different it'll sell tepidly here just like all its (numbered) bretheren before it.
