Summary: Absolutely fun! For both adult and kids. My son is only 4 and he enjoyed just watching us play the game. Its still pretty difficult for him to do the controls and I thought he could do this. nevertheless, he absolutely enjoyed watching us play the game. I got my mom into this and she is 62! After leaving our home, she had to buy one from Amazon too for her Wii and is hapilly still playing it :-).
Summary: My sons (5 &3) love this game! The single player game is their favorite. The downside is that they don't have great 2 player games, so my boys always end up taking turns with the 1 player game because they "hate" the 2 player games. but I would still recommend! Decently priced!
