i would also go with xbox for sport games, and more grown up games, the wii is great for multiplayer fun stuff, don't know bout the sport games in Wii tho, wii is definately better for family fun and will probably be used by your kid the most if you get it. The xbox has a more complex controller although it does not have a motion senser like the wii, it has more buttons, which could improve gameplay but might take more time to get used to. Also the xbox definately has more fps and better ones, meaning for more mature audiences, but there are plenty of games out there that are kiddy like, i guess you could get dance dance revolution if you want something for your kid, lol. i wouldnt even consider ps3, sorry all you ps3 lovers, it is only good for blue ray and a few select games, also if you plan to play online xbox costs every year bout $50, but it is far better than ps3's online, which is free. If you do get wii i would suggest super smash bros. brawl. Roommates and i play that all the time, i'm sure your kid would enjoy it.
