Xenosaga's primary issue is that it's trying to appeal to the niche fetish-anime crowd, while also wanting to be taken seriously as a sci-fi epic. It accomplishes neither well. Xenogears was far, far better an attempt at this, despite its problems. By Xenosaga 3 a lot of the issues were fixed, but it was, in my books, too little, too late overall. It's still a good game to play, but I felt very cheated by having to wade through two awful games to get there.
