Get the Deluxe if you're planning to play with friends often or need alot of memory space. Otherwise, get the Basic. And wait until the price drops to get Nintendoland if you get the Basic, it's currently retailing at 60$ in the United States.
I suppose I'll say what I say to most of my customers: You'll end up needing an external HD later, might as well save some bucks... and forego Nintendoland unless you REALLY like minigames, 'cause that's all it is. A couple good ones, but not enough to make it worth what you pay. Plus, the black model shows fingerprints like a futhermucker...
Don't get Nintendoland, it's stupid. As far as the memory capacity goes, if you're like me and you tend to play a small core group of games, like five or less, you won't need the 32GB version. There was a large download in order to play Wii games but I only play four core games at the moment and I still have space left. Keep in mind, however, that all your original Wii games also save to the system memory. The 8GB version has an expansion slot for an external memory if you need that extra memory space. Save the money for the good games. If you're a hardcore gamer however, meaning more than five games with frequency, than you might need the larger version.
I don't like that new wii u/we u/ we you/ weeeee uuuuu/ weeeee yyooouuuuu. Look at that 4 ways of saying it and and there's only one way to say it if you want to screw the name up. Where did they come up with that weird name.
