My sister usually plays the newest Professor Layton for a little bit, but never finishes. If she's really bored in a car ride, she'll play a Mario game.
My father doesn't play games, but a few years ago we would play an occasional multiplayer game. Very occasional.
My mother used to play Pac-Man World 2 with me when I was younger. I think she used to play arcade games all the time, but now she looks down on video games in general. Sometimes she watches me play if we're in the same room. If I'm playing an Xbox game, she'll make a comment on how the graphics are much more advanced than of the Mario games I usually play.
