Blast it Jeeves, this psychology rubbish is going to wind up with you in the muck if there isn't soon a concerted effort to take considerably more trouble to watch exactly where the feet on your head are taking you.
Er, sorry.
You've got excellent points this week Yahtzee, but it's the ending bit that really did it. Why do any of us like Hamlet? Or Othello? Or Falstaff even; we all project a bit onto fictional characters, and any real enjoyment is either surprise (comedic or thrilling) or vicarious reward. In a movie or a book or a game, the character I like and their accomplishments make me feel good. When the character I like in a game kicks serious ass, or the chap in a film manages to swindle the casino, or when James Bond in anything kicks ass/swindles the supervillain/gets the girl, we eat it up. It's psychological self-preservation, making us continue to believe as ever that we are, in fact, awesome, and by identifying with anyone who's succeeding at something we wish to succeed at, we get a mental benefit too. Anyone who isn't competition allows us to feel vicarious reward, and it's a great sensation.
But it is to be completely self-absorbed and ignorant that allows us to be so and not analyse or pay attention to just what we're vicariously enjoying, and we all have a disposition towards that ignorance that allows for just such a positive stimulus to work in the first bloody place. When a movie makes you feel good, look at why. When a book makes you feel good, look at why. When a game makes you feel completely fucking unstoppable, or deft and skillful, or silent and unnoticed as a night breeze, look to the why. Why else are Die Hard, Twilight, God of War, and countless other successful entertainment ventures so resonant with the masses? Star Trek, Star Wars, Dune, Final Fantasy, Mega Man, Super Mario, Harry Potter, Robert Langdon; all successful franchises or characters because of the way in which we allow ourselves to inhabit the specific people presented to us.
