I think it is possible for a person to change personality when he/she gets too attached on technology?
I'm a gamer and I prefer violent gore games when playing on my computer, I think that affected that way I speak and treat others in a more aggressive way and IT's really not a nice change.
I don't think it affect your personality. Games are just games and it should end there. It's not the games fault if someone treated others aggressively. There are a lot of factors why you are reacting that way. Maybe its because you know that no one will fight back or you have a problem and you just want to get away from it by means of doing that. Even if you are not a gamer or you play non-violent game, you will still have the same attitude and will react the same way.
