to be Call of Duty & Medal of Honor? might be tough to ban those even if your household doesn't own them. Plenty of good sports & driving games. The mice will play when your away. We let teenagers play the shooter games by renting them, but w/ time limits and as a reward. IMO, it's the extremes, as w/ anything, that cause the problems. Hours and hours nonstop playing, and 6 y.o.'s playing the bloodiest of games. I don't kid myself by thinking we know and see 100% of what they're playing, but they know the rules.
Looking back on my childhood, it seems the extreme forbidden focus on certain games or movies backfires by creating an obsession w/ the forbidden. Not saying no rules, but a balanced, logical, matter of fact tone seems to eliminate some of the phenomenon that kids get obsessed and super strict strategy backfires from a parenting standpoint. From past CB discussions, I know some don't agree w/ that take, but I've seen it too many times and think it's very much a factor. Especially with sexual or nudity themes. "Meh, theres nothing to see here, move along" type thing. We've only owned PS products since the Atari, Coleco-vision, Nintendo days of my yoof.
