I actually think it might be the opposite, that what games we play (and what games we make) are determined by the values we hold. I still don't like playing games where you're a villain, and it is why I have never gotten into certain franchises.

At least, to what degree those do relate to real life morals at all. Because I certainly sometimes take actions in games that I wouldn't condone in real life. Such as walking down the street killing "innocent" guards in Assassin's Creed.
