Passing an age milestone doesn't bring spontaneous maturity. I respect what you're saying, but from personal experience I've found younger players (not 12 year olds, around 15-16) to be much more friendly than adults. Adolescence is innocence, after all. Restricting a game based on age is just as discriminatory as not letting a certain gender play it, in my opinion. Everyone is different and acts differently, you'll find griefers wherever you go in sandbox games like this. It adds to the survival element and regardless of my not being a bandit, I can say that I like it.
