My just turned 6 yr old likes the sports games the best- they seem to be the easiest to play. He actually likes the one that comes with the system. He also likes the cooking mama game. We bought cars- but the wii version is a little rough to figure out. We have rented:
Spongebob- i thought tough but we aren't big gamers
Paper Mario- a lot of reading.
Another Mario game- which was great
I like using the game cube games on it as well- lego starwars is a huge hit, as are the original mario brothers games.
When you use the Game Cube games on it, do you use the remote that comes with the system, or do you have to use the more traditional looking remote? I did not realize you could play those games on the Wii! GREAT... something else to think about! LOL
