I mean, for Roshutsu it makes sense, since Roxxane was based on that game, and itself has been on a indefinite hiatus when it's dev decided to make another game. Now this game(NR3D) has been cancelled too for Calculated Risk or whetever is the name of it's "successor". And even Roxxane has been scraped to restart developing. Seems to me that all naked stealth games are on a hard time, since most got scrapped to be restarted or got put to the side for another thing.
