Hah! Uh well.
Anyway, You know, I think there is something I really would like to explore narratively, however I think that isn't really easy to achieve. Imagine if your son would actually be your mirror. Depending on your actions in the game he would be either a hero, or a villain that you have to fight - and beeing truly neutral leading to a very different ending would be kinda the "hidden" ending. The choices have to bee not hamfisted though and more subliminal requiring good writing, so you don't get at the first time you're playing the game.
