Personaly, I do not think videogames makes a person violent. I'm a gamer myself but I do not see myself getting violent or developing any violent tendencies. On the contrary videogames are stress relievers for me. So I consider people saying that videogames makes a person violent as either ill informed or biased against videogames. Admittedly, being a gamer my response is bias too. Anyways, that's just my opinion.
