I've recently become concerned because my children have started playing video games that are a little too violent for them. Since my and husband and I work a great deal of the time, we aren't home when they get home from school, which is normally when they play their video games. Night time is homework time, so when we're around the house they're not playig them either. My kids get very good grades in school, so I feel bad taking them away because they should be rewarded for hard work in school. But since I don't even know how to turn on or play their video games (my husband has all these crazy buttons and remotes), how can I ensure they're not too violent?
