The only games I play is the pinball and reversi that came with Windows, and I haven't played those for over a year. I bought my daughter a PS2 last year, and it has only seen occasional use. It has been at least a month since she turned it on. She has plenty of games, but gets bored with them quickly.
The best gift I ever bought her was her laptop. She has used it almost daily every since I bought it for her three years ago. She loves the wireless feature, because she can surf the web from anywhere in the house, and even in the back yard if she wants.
