Sam Barlow, lead design er of Silent Hill: Shattered Memories has given his views about On-Rail shooters. They come in response to comments from Capcom and SEGA concerning mature games on Wii.
Speaking to Official Nintendo Magazine:
Without badmouthing people, a lot of the games they've been complaining about are rail shooters and a rail shooter wouldn't have sold no matter what platform you put it on because it's a rail shooter and that's a niche genre that had its heyday back in the Dreamcast era.
Ultimately the way we looked at it was that there's a huge audience who own Wiis, we own Wiis and we know that amongst that audience there is a sub-sect who love dark stories, thrillers, mysteries and horror movies and so the development of Shattered Memories was all about removing the obstacles to those people enjoying this game.
If they really enjoy a good horror story, they should enjoy this so we've tried to create a product that has broad appeal but does something new.
