So I bought a Wii U!
The pack-in game is Nintendo Land. It's a pretty fun little collection of minigames, but I don't think it's
quite the tech demo Wii Sports was. Now I'll have to do a little review of each game in no particular order oh boy oh boy
Donkey Kong Crash Course: You have to guide a small kart through a 2D obstacle course using the Wii U's many ways of input. Tilting the gamepad moves your kart around, pressing each shoulder button moves some platforms, moving the left or right control stick moves some platforms, blowing into the mic moves some platforms. You can collect bananas and coins (though the bananas don't add anything to your score, I think...) and your goal is to progress through each area and get to the end. Slightly glitchy, though that might be part of the OLD-SCHOOL NINTENDO DIFFICULTY. Single-player, though I've heard a second player can help.
Octopus Dance: Dancing with the Game and Watch octopus, kind of like Simon. Move both control sticks in time with the rhythm. It's kind of entertaining for ten seconds. Single-player only.
Balloon Trip Breeze: It's everyone's favorite part of Balloon Fight, now with Miis! You move your little Balloon Fight man around with the stylus, and avoid hazards and enemies. You can send your enemies into the sea by popping their balloons, or breaking blocks underneath them. A good bit of fun if you like Balloon Trip (I don't, really). Single-player.
Yoshi's Fruit Cart:You have to collect fruit with a Yoshi-looking cart. You do this buy drawing a line on the gamepad which the cart travels along and collects the fruit. Much less fun than it sounds. Single-player.
Takamaru's Ninja Castle: Remember the all-time Famicom disk system classic
Nazo no Murasame Jō? Of course you do! In this game you fling shuriken from the gamepad at ninja on the TV. Neat idea, but not all that fun. Single-player.
Captain Falcon's Twister Race: Race along some tracks with your Mii in a silly Captain Falcon costume. Hold the gamepad vertically and tilt it to guide your car through the track, avoiding obstacles. Seems like a cheap iOS game, and reminds me that the last F-Zero came out eight years ago.

Single-player.
Mario Chase: It's tag with Mario characters, just what you wanted!!!! One player, dressed as Mario, looks at the gamepad and runs away from the other players, dressed as Toads, tracking their location with a map. The Toads must catch Mario before the time limit is up. Mario uses the gamepad, Toads use Wii remotes. A lot of fun with five people, actually! 2-5 players.
Luigi's Ghost Mansion: Now we're getting into it. One player, using the gamepad is a ghost. The other players use Wii remotes to control their Miis. The ghost hunters must shine a flashlight on the ghost to take away their health, and the ghost must attack each of the players. Here's the twist: The ghost is only visible to the person controlling them on the gamepad. The other players can detect were the ghost is when their remote starts vibrating, signaling that it is near. A great time with five people, any less and the AI makes it a chore for everyone. 2-5 players.
Animal Crossing: Sweet Day: The player with the gamepad controls two guards, each with either control stick. Their goal is to catch the other players, dressed as animals, who are depositing candy into dishes for some reason. If the animals can put a certain number of pieces of candy in the dishes, they win. The guards' job is to tackle the animals, and take away their hearts to win. Pretty mediocre, but give it a try with the right number of people. 2-5 players.
Pikmin Adventure: Gamepad player controls Olimar, and the game plays pretty much like Pikmin with touch controls for that player. The other players use Wii Remotes to control individual Pikmin, who can attack, grow and collect power-ups. There are several levels to play through, some timed, some boss levels. Quite fun with others, but you can play by yourself if you just want a pure Pikmin Wii U experience. 1-5 players.
The Legend of Zelda: Battle Quest: First person Zelda. Gamepad player controls a Link with a bow and arrow, and the Wii remote players use a sword to fight enemies and bosses. Not the best alone, but pretty fun with friends. 1-4 players.
Metroid Blast: Basically a third-person multiplayer Metroid Prime. Gamepad player controls a flying spaceship while Wii remote players play as little Samuses (Sami?). They all play together in co-op endurance rounds, and versus deathmatches. A lot of fun, with or without other players. 1-5 players.
You can collect coins in these games to buy items that furnish your overworld, and eventually other Miis from the Miiverse walk around your overworld. It's quite fun to see how many of these items you can get, and then show off your collection!
All in all, I like Nintendo Land a lot. I find it a ton of fun with friends who are skeptical about the system, and it's a nice way to get me introduced to the Wii U.
