In the defense of the game known as Skyrim, I have to say it is clearly not harming the Christian, or Child based groups.
The game itself does not encourage anyone to do harm unto others. The game itself may have you do tasks that are looked down upon by society, but alas it doesn't however give you the need to go out around town and do them. It was a game made for entertainment, not for anything else.
For the Religion community, sure it show a polytheristic religions based on gods that represent different aspects but it does not encourage the worship of multiple gods.
For family such as kids or teens it has a rating for the parrent or young adult to examine and decide if they should let the child or themselves play the game in the first-place. If you have a problem don't buy it.
