The Wii system is actually a great system for the younger set. My 5 year old step son LOVES the Wii, as does my 8 yr old step daughter...and my husband!!
We have Mario Party 8, Super Mario Galaxy, Dogz 2, High School Musical, M&M Kart racing, My Sims...and a Carnival game as well...oh and Wii Sports.
the kids LOVE Super Mario Galaxy! Mostly they sit next to my husband while he plays. My step daughter plays second in command and collects stars while her little brother watches and dances around in glee at all the action on screen!

They love it!
It can be a tough system to get. A lot of places sell them in "bundles" with games you don't have a choice about for $600+!
My husband and I had to go all the way to upstate, middle of nowhere New York...where his parents live to get one for the regular price of $230! We had to get up at 3am on BLACK FRIDAY...wait outside in the FREEZING cold at Wal-mart in a line...wait INSIDE until 4:30 am...and then we had to RUN to get one of the 20 they had for sale. It was nuts. I still can't believe we did it. My husband got #17 of the 20!

(Actually he didn't really have to run...he has long legs...so he walked quickly in a dignified manner! He did get bonked in the back of the legs by an elderly lady with a shopping cart...but he didn't push back...very much...

)
It's a fun system! The kids love it. They play with it a lot and bond with their daddy! It's a very family oriented system!

Especially when wicked step mom turns it off and shoos everyone outside for some exercise and natural light!
