All this talking about getting M rating is stupid. Did they want to "protect some young gamers from not-very-happy-endings", so they would not cry or try to kill themselves?
Imho, the shock from knowing that the ending was cut is much greater.
Or they could make one happy-ending, where PC marries Visas, Handmaiden, Mira, Krea (what? maybe someone likes her) or even Hanharr (if they want some exotic relations)
And make all other sad endings for us.
It is like reading an interesting book, and when you are about to finish it, they say:
Sorry pal, but this book does not have the last chapter. But we can tell you what happened in it - galaxy saved, Mira dead, exile lives.
Man, that's sux
