I don't think you did. Saying something is worthwhile isn't inherently a comment on its quality. In fact, I don't particularly like these kinds of games. However, enough people enjoy the genre and games for Tecmo Koei to keep making them. Otherwise, they wouldn't keep making them. That makes it worthwhile to me.
Despite your disingenuous comments, I'm sure a lot of people will enjoy this game, even if it just for Link.
