For those ages the Wii is perfect. The Wii Sports that comes with it is a great starter. It comes with one Wiimote and one Nunchuck. You will want to get AT LEAST one more of each, end goal should be owning 4 of each (though it gets pricey quick, I recommend working up to it slowly). The Wiimotes sell for $39.99 at most locations, and the Nunchuck is usually $19.99. If you buy Wii Play, a collection of 9 minigames such as pool and pingpong, for $49.99, it comes with a free Wiimote in the box. So basically it's $10 for 9 mini-games. Not too shabby. I recommend Mario kart. I the classic is even more fun on the Wii. It comes with one wheel that you plug your Wiimote into. The wheel is not required to play the game, but certainly makes it easier/more fun. As sometimes mentioned, and UnitedRam can attest to, it is also a blast for the 20-somethings, so long as you aren't looking for the best/most detailed shooters and RPGs. One game I found interesting was Boom Blox. It is a puzzle based game, multiplayer. I played it with my younger cousins on a family vacation, ages 8 & 11. Players take turns throwing an object (I think it was a yellow ball but I can't remember for sure haha) at a stack of blocks, with various point values, knocking as many blocks off the formation as possible trying to receive the highest point total. It's very simple to learn and gets pretty competitive. My cousins really enjoyed it, and I have to admit, even I had fun playing it. You should be able for find it fairly cheap used as it has been out for a while now. Also, I've heard nothing but positive things about the WiiFit, though I don't know how well it is received by the younger kids. Walmart's deal with the $50 gift card is great. I believe that you have to use it on a different transaction, but you can get them to ring up the system, then use the gift card for additional games, Wiimotes, and/or nunchucks.
