I have not played any of those on my wii. Though my four year old daughter, 8 year old nephew, and 10 year old niece like the following games:
Carnival Games- (somewhat difficult for my four year old, but does ok with help)
Sonic- (We just got this from the best buy- $19.99 deal- my daughter loves it)
Wii Play- (I don't have this but my nephew does. My niece says that this is all she plays at his house.)
Honestly, I don't care too much for carnival games, but when my niece is over that is all she plays. It used to be wii sports. All my daughter wants to play is sonic. She can do some of it without many problems. However, I would say that you couldn't just sit a five year old in front of the tv with this game and walk away, expecting them to know how to play it. Never played wii play so idk.
As far as the other responses...my nephew loves excite truck. The other two havent played it but i'm sure that would be a winner. And as far as Mario Party 8 goes, my kids loved 5 and 6, so I'm sure it would be a winner as well.
Personally, I tend to stay away from movie-tie-in games and I heard that bust-a-move bash has VERY frustrating controls. And I don't know about Marble Mania. Hope I helped.
