We bought a Wii for our 7 year old son, for Xmas. He loves, I enjoy it as does the wife.
Max, get the Wii, you at least get off of your a** when you play it. Although, I've perfected Baseball and can play from the couch if I wanted too, but I stand up. They DO have a Component Video for it, but you do NOT buy the Wii for "graphics". Although, I've been told the latest Tiger Woods Golf for Wii is nothing short of incredible.
If you get the XBox/PS3, you're not thinking about "her." I guarantee you as a Married man myself, that card will be played soon after purchase.
