Let's get this out of the way: Oblivion rerated

I don't want to waste much typing on this because it's annoying, but Elder Scrolls: Oblivion has been rerated from T to M because of a mod for the PC version that makes the main character (if it's a woman) topless. The ESRB (the ratings board) also gave some bollocks about there being more violence than they thought at first, but come on. It's not clear why the Xbox 360 version was rerated if the mod is only for PC. Anyway, if you want to read more go here and here.
