That's right folks. It's a game. Nope, there were no real actresses used. It's a game. (Though Youtube doesn't do it justice. I have a high-res version.)
Now, forget for a moment, how graphics seem like "nerd" stuff. Forget for a moment how this is a PS3 game, (I am so getting the PS3 just for this. O levels = 6 points.)and think.
Man really has made plenty of achievements. I always thought photo-realism was impossible. It could not be replicated. People cannot be realistically portrayed in a game. In a movie, yes, because scenes are pre-rendered. Meaning, everything will happen as planned, hence more resources for emphasis on graphics.
In a game, however, there is no "script" or dogma to adhere to. Different players will do different things at different times.
I can only imagine how man would advance in the future. Breathtaking.
