Mine's pretty okay with it. She wishes that I'd save more and says that I've got a lot of stuff.
On the other hand, if I ever start selling something, she starts quizzing me to make sure that I *really* want to sell it and that I won't regret doing it. She also knows that I manage my funds enough to pay the mortgage, keep saving on my RRSP, pay for most bills and expenses. Granted I do occasionally need her help now and then with groceries, but that's usually during tight months [5 mortgage payments + property taxes] and I don't usually buy games when that happens. (Considering that she lives with me, she doesn't have many living expenses to deal with. :P)
She does occasionally play some games (Animal Crossing, Super Monkey Ball, Windjammers, Puzzle Bobble, Metal Slug(s), X-Men Jamma) and seems to like it when I get around to actually play games. (I don't have much time lately.)
