for that age group a wii will win every time, if you are buying new, try and get a deal that includes wii play, its some fun little games but you get another remote and its only 35 (its 30 just for the remote) to play 2 player boxing (included with the wii) you will also need another nunchuck, about 15

bowling is excellent aand thats also free with thw wii its on wii sports wich is boxing,golf,bowling,tennis and baseball

standard sd card but you dont really need one unless you plan on downloading older gen games from nintendo and paying for the privalage, another handy hint for that age is, buy a couple of gamecube controllers and you can get some classic gamecube games ie mario kart for next to nothing in the game shops, the wii is backward compatible
hope this helps
