DS Daily: Sibling rivalry

For those of you have siblings -- whether you still live with them or not -- we thought we might ask about your gaming relationships with them. If you're a little older now and living apart, we're curious as to whether or not you both grew up gamers, and if you liked the same sorts of games. For those of you who still live with your rivals siblings, we pose the same questions, but we also wonder if you guys play together ... particularly when it comes to DS. Is everyone packing their own unit, or do you have to share?
