Generic, boring, and more importantly, not much fun to play at all.
Carnival: Funfair and Games is another one of those poor forced efforts to make a family game for the Wii, but, really, it's not an effort at all. Carnival is a game that is just a bland and rather generic arcade game, not really adding anything new into the mix, and just is a game with a huge lack of anything fun in it.
The thing that truly prevents Carnival Funfair and Games from being a family classic like Wii Sports is what the game is about in general: going around playing arcade games to win teddys, not very orginial or more importantly engaging to pick up and play.
Overall, Carnival Games is a game that will bore any likely player, due to it's lack of fresh content, and overall, a poor execution that does not make it very fun.
