I have played and played and played all the attractions for this game, and I would like to post a short "review" of all of them, in no particular order.
1. The Legend of Zelda Battle Quest: Provides a pretty fair challenge, especially after Ganon. It is very fun to play with your friends, you feel pretty cool as a small "army" hacking, slashing, and shooting your way through every enemy.
2. Pikmin Adventure: I really like the design of the Bulborbs in this one. It is a fun attraction, but isn't as difficult as the Pikmin games. I suppose this is a good thing, however...
3. Metroid Blast: This one is a blast (pun completely intended). Seriously, it is such a great time to fight either on foot or in a spacecraft. It controls very fluidly and can be difficult, but is fun no matter what.
4. Mario Chase: I have one complaint with this attraction: The Yoshi carts are pretty overpowered. It makes the game a bit unenjoyable to be Mario and get caught (very easily) by the Yoshi carts. With a group of more than 2, however, it is very hectic and fun.
5. Luigi's Ghost Mansion: Very interesting to play Luigi's Mansion from the ghosts' perspective. This minigame has very nice atmosphere, smooth gameplay, and overall is a great time to be had.
6. Animal Crossing Sweet Days: Probably the only attraction I dislike. If you have 3 or less people, the guards almost always win. If you have more than that, the animals almost always win. It is kind of broken and was not much fun every time I played it. A shame too, since Animal Crossing is a lot of fun.
7. Yoshi's Fruit Cart: An interesting concept that uses the gamepad very well. My sole complaint is that the game is repetitive and gets stale quickly.
8. Balloon Trip Breeze: It was a lot of fun watching my friends fail at this. XD Fun game.
9. Donkey Kong's Crash Course: Definitely the hardest game. But why can I not go straight to area 2 after beating are 1 for the first time? Why must I beat it again? Every time this game has proven a challenge, no matter who I play with. And you know what? I like it.
10. Takamaru's Ninja Castle: A simple shooter, but I really enjoy its control scheme. Using the GamePad in this way was innovative and fun.
11. Captain Falcon's Twister Race: Whew. When they said daring, they weren't kidding. However, I did experience some issues when making sharp turns. Sometimes when I would make the sharp turns, the GamePad's calibration would get messed up, and holding the GamePad horizontally made it go straight. Still fun, but this minor issue is a setback, but not a deal breaker.
12. Octopus Dance: A simple rhythm based game. But where does the octopus take you if you mess up enough times...?
