So you're saying that there's two different genres of games that happen to share the same name? A bit like "hard core" music, I guess. Except "hard core" has a meaning outside those genres, whereas "roguelike" explicitly refers to the first game of one of those genres, and I don't think the other genre ever had a game by that name that defined it. So it's basically just trading on the name of another genre.
