The purpose of fiction is to help you escape from reality.
This type of one-liner irks me, as it almost sounds apologetic - in my view fiction is part of storytelling and part of reality, not something completely set apart from it. It can help you escape to a fantasy world where happy-holly is going on, or it can reflect on reality. It can tell you something about your daily life or the world in general.
Most games may actually
not tell you anything about anything and offer you nothing but bland and repetitive amounts of 'fun', of course, but I think that is rather because on the whole games are immature than because fiction on a whole can offer nothing but that.
...no, I don't like Mario Cart.
Realism is relative as well, Tim Schafer may write games about the land of the dead and psychic summer camps, his game are terribly 'realistic' in the sense that characters and situations are etched out. The world is surreal, yet the characters are real. In that regard many war games have a real world but surreal characters that are made out of cardbox.
Regarding realism and Psychonauts: The memories of the various people you meet, agent Vodello in particular, really connect to me on a human level that I haven't seen any other games do. I think that is some 'realism' on a human level.
All in all I value realistic characters and consequence a lot more than guns making the right sound of 'pow pow pow'.
