Watching porn did not make me a better lover
Playing video games did not make me into a killer
Reading the bible did not make me a christian
Listening to music did not make me understand how to play an instrument
Eating good food did not turn me into a gourmet.
People are responsible for how they "turn out";Not what they read/watch/play.
Getting back to the specific OP topic, there is a reason why they are called Roll Playing games and not True Personality games.
