As for Americans preferring guns over swords, that's a load of crap. If they ever got a translation team together, this could sell real well. Also SWD3 probabily the most disappointing game in the series, although the easiest to translate. On the other hand Pal is a legend that I doubt you can translate even half the game. Also Kenshin is cake to translate compare to stories embedded with cultural underline and mythical meanings.
RPG sales are at a low point in the U.S. compared to shooters and racing games.
Everyone saw Myst, everyone saw Final Fantasy, and then everyone realized that if they want pretty scenery they should go outside and stare at the real sky. Games in this country are for doing exciting things and exploring roles which aren't anywhere near real-life, which are more exciting and fantastic than daily life. The only reason the computer RPG evolved at all is that early systems couldn't render immersive three-dimensional representations, so you navigated through text or icons to interact with the virtual world. Heck, half of the people posting in this thread were erroneously thinking this RPG thing is a first-person 3D game. It's a cultural thing.
