I'm really not too worried about same sex relationships. My son plays for fun, and if situations arise that he doesn't understand he asks questions about it.
I'm not going to digress into what you should or shouldn't do. Everyone parents their children how they seem fit, and that's not the point of this thread. I understand and respect everyones' choices.
The big thing is he gets to live his Star Wars fantasy and have fun with his old man. As they kids get older they tend to move away from bonding time, but this game gives them something they can do with their parents and still seem "cool".
