This has also been suggested on the minecraft forums. Minecraft should also be on the wii. But, Mojang has signed a contract with Microsoft to not go on any other platforms.
My solution to this is for Nintendo and Microsoft to agree on letting each other license minecraft. In this case, minecraft would be able to come out for the wii and wii U.
Now, the controls. You would need the nunchuck. You use the steering pad to change your view. You use A to go forward, B to go backward, - to open your inventory, + to pause, 1 to go left, and 2 to go right.
If I have forgotten anything on the controls please tell me. Thank you for reading.
