My parents never had a problem with me playing videogames, even violent ones. In their opinion, they'd rather have me using my brain for problem solving, strategic thinking, reading, etc. than just being a vegetable watching crappy TV shows. As far as the violence issue, they knew I could tell the difference between make believe and reality, and that I would never hurt someone in real life. It's just like boys playing cowboys and indians or cops and robbers 50 years ago, there's a difference between play violence and reality. Most kids know the difference. If they don't, then there are more serious problems than what videogames they play.
