"The entire game is vile. The amoral nature of the graphic violence is far worse than the sex scene."
yes I agree the context of the violence is more disturbing to me than any sex scene but from what I understand [since I dont play it I stand to be corrected] the game intends for you to play at violent criminality as a violent criminal 'thug' character...that is not Amoral violence but IMmoral violence imo.
Contrast with "Star Wars: Knights of the Old Republic" [which I do play and is my favourite game next to Halo] which can perhaps be more fairly described as Amoral...in KOTOR one has the MORAL CHOICE to develop your own character and play as either a 'light side' Jedi or turn to the 'dark side' of the Sith...and there is a well developed system of MORAL CONSEQUENCE that affects gameplay following from one's choices...yet one CHOOSES which path to follow [I choose the light side for my character Kel Fyr] and can 'win' the game either way...but what kind of 'person' your player character becomes is determined by your behavioural choices...just like in Real Life.
This imo is better than a game like GTA that if i understand it correctly forces you to play as a murderous thug character...if you could as easily play and succeed at the game as a COP protecting the citizens of San Andreas from murderous gangsta thugs like the main character is THEN maybe GTA might interest me.
