Give the gift of Unity
As the Unity team prepares a new 1.2 release with mondo new features, like full-screen graphic effects, and a drop-in FPS controller, just in time for the holidays (hopefully), consider giving the game development tool as a gift. In fact, the Unity site posted a how-to on creating your own boxed version. Just print the templates, grab some scissors and blank media, and voilá! Unity, and perhaps a book on game development, would make any wanna-be game developer in your family happy. Except that most game developers use PC's. And since Unity can only deploy games on a PC, not create them, you might need to pick up a shiny new Mac for that loved one as well. No, I don't work for Unity, but I am a big fan.
