I think the explicit difference between Chris Hansen-addled fanservice and glorified ultra-violence as in Mortal Kombat, God of War, etc. is mostly due to the age / willingness of the participants. In Mortal Kombat, for example, you have characters duking it out with the definite intent of trying to kill one another in a typical match - obviously none of the characters want to be on the receiving end of a fatality, but they're all making the decision to fight in-universe and understand the possible repercussions

Can you really consent to participating in an interplanar competition when not doing so assures the destruction of your home realm?
