Based on a horror movie that came out in Japan, Sweet Home followed a team of investigators that explored an old house full of ghosts and monsters. The story was disturbing, concerning a lady whose child fell into the furnace. She then killed a bunch of other children and burned them in the same furnace so her child would not be lonely. She later killed herself and came back as a ghost, haunting the estate.
It's easy to see why the game never came out here back in the day. Nintendo of America had a stricter set of rules than Nintendo of Japan. What was acceptable in Japan, be it violence or nudity, simply would not fly in America. That's just the way it was. You gotta figure, this was before the rating system. Plus, Nintendo didn't want any of their games to end up like Atari's adult themed entries, where they were hidden behind the counter away from public view and purchsed by request.
However, times have changed. With a ratings system in place, Sweet Home could easily come to American shores. In fact, in some ways, it already has. The game can be downloaded, and fans have translated the game. Also, some really creative guys have made it available for mail order, in classic Capcom packaging, also including a map.
Still, I'd love for this game to be available on the Wii U and the 3DS. I'm sure a lot of other people would love to see this, too.
