My grandma (before she died) used to play PS1 all the time. Her husband died a few years before and she was "lost". I went round to see her and she'd gone out and bought a PS for the "grandkids" and when I set it up for her she wouldn't let us have a go, LMAO. She used to love it. My mum is 50+ and she still plays games, I buy them and then when I've finished them she'll borrow them and finish them too!!
My friend's dad pretty much does nothing but play BF2 and taunt all of the younger players (or whatever he has on his Xbox 360) all day, and it annoys the crap out of her. Of course, her dad's retired, and has pretty much nothing to do all day.
