I got one. So far I have Nintendoland and New Super Mario Bros. U. The latter is quite fantastic, assuming you like the standard Mario formula, but it doesn't do any interesting gameplay with the controller(though being able to play the game with video on the controller if someone is watching TV, is handy). I have not tried Nintendoland yet, been kind of busy this past week and I need to actually get some Wii remotes and nunchucks again after selling my Wii to a friend earlier this year.
Right now the launch period games I want to get, include Scribblenauts, ZombiU(With the mixed reviews, it will be a bargain bin game in less than 6 months and Ill get it when its $20 or less, but it looks interesting), Rayman Legends, and Pikmin 3. Maybe Lego City Undercover if it gets good reviews. But I really look forward to the post-launch lineup games and seeing what gets announced for the console at E3 next year. Plus, you know, the inevitable Zelda, Mario Kart, and Smash Bros. games, hopefully a good Metroid title and 3D Mario, and would love to see Nintendo bring back F-Zero.
Launch lineups are never all that great, for any console. Between the multitude of ports and all the games being the first time the developers have worked on the system, things tend to get better over the following years, but Nintendo systems are safe buys for me even at launch because I know they will eventually get exclusive games in franchises I love.
