I've always wondered why there were no children in oblivion. I mean, they could have just made them invincible like in fallout right?
Of course, there is also the easter eggs around that suggest that children were going to be put in the game:

"M'aiq believes the children are our future. But he doesn't want them ruining all of our fun."
and the small child like skeletons found in the night mothers tomb

Killing children = A bad game

Actually I think it's more like children killing = prohibitive rating from ESRB.

You have already had one topic like this closed where child killing has raised its head. It is a restricted topic, do not make any more.
