I don't even know where to find a friend code...does the WiiU use friend codes? I don't even know that!
Edit: (looks in the online ID thread) OOOOOOOhhh it's that Nintendo Network thing, ok. Added to the thread.
So anyway, NintendoLand. I think I've played everything but the octopus game so far. Most every thing is at least decent (I assume other people like the Ninja game, I just don't like the mechanic of throwing the star), and the Zelda and Metroid games are awesome, and they're both single and multiplayer. Metroid I haven't had much of a problem so far just playing by myself, but Zelda is much easier with two people. Especially since I like to play as the archer and that's tough alone.
I get the feeling it's going to take forever to unlock all the themepark accessories (and fuck that coin drop game you play to unlock them), but I'll probably do it because I want to unlock all the music for the jukebox.
