I would say in this order:
Kids and Games. My kids never nagged me for it. I thought it would be a good system for them to play games on which would not intefere with my computer game time. I also like certain Nintendo games. I played the hell out of, and still play, Rogue Leader. I also like Smash Brothers, Metroid, and Zelda. Other than that it's for my kids. I don't play on it much, but it's good for a quick distraction.
