Should fathers play video games with their children? God, I hope so. Although, I myself am not a dad, I am a parent and both of my children can sing "Shout at the Devil" because we let them play "Guitar Hero II" with us. Aw, come on. It's fun for the whole family. Didn't we all play Pac Man with our dads anyway? I know I did.
Anyway, there are various theories on how beneficial playing video games with your kids can be. A lot of dads feel like it is a great way to bond with their children. Some experts insist that these kids will not develop proper social skills.
I say a lot of it probably depends on what kind of game you are playing. I'm guessing if you are playing Grand Theft Auto with your five year old it probably isn't that healthy, but if you are playing some interactive educational age-appropriate game with your child it can be a great way to spend quality time together, especially if the weather is crappy.
Just save Manhunt 2 until the kids are at least in high school.
