Just fantastic, brings back so many memories, and just so damn fun with friends.
Also you can use the UK code with the UK Nintendo club to get the free game code while the promotion lasts. just make a second mii login with the location set to UK, then enter the code to get your free game, and once its installed just go back to the normal NZ mii login.
I have been enjoying Mario Kart 8 and Free Super Mario Bros U. :-)
