Grab the joystick? Don't mind if I do...

Recently, I read an article called "Grab the joystick: toy with your man in the virtual world". According to the doctor in their study, "playing video games allows you to bond and learn how to problem-solve as a team". While Peter and I have definitely spent some time playing games together, most recently WarioWare Smooth Moves, we seem to alternate between laughing hysterically at each other's mistakes, and arguing when the other one messes up. So while I do think it helps us "bond", I'm not so sure about the problem-solving as a team part.
