Look at it this way. They could be playing something stupid instead like Call of Duty that is just mindless shooting and doesn't engage their brains or let them use their imagination.
Yes that is very true! They have asked about getting more COD games. I admit I like playing the shoot 'em up games has just mindless relaxation. At least they are not *too* into the COD, they play other type of games just as much as COD.
