That is SO true! We rented Call of Duty II for our son and his friends, since his birthday was this past weekend, and my husband was 'hogging' it most of the time! They finally had to hide it when they went to do something else, because once Dad started playing it, the boys couldn't get it away from him, so they could have a turn!
My husband is also 30(something), a Brilliant Professional Engineer, that LOVES Gaming! As a matter of fact, when we have games in the house, it's as though I have FOUR kids, instead of three, because he is right there with the kids, arguing about who's turn it is! (I usually end up having to take the game away from all of them, and not return it, unless they can work it out nicely). LOL.
