Minecraft is a three-dimensional sandbox game that has no specific goals for the player to accomplish, allowing players a great amount of freedom in choosing how to play the game. However, there is an achievement system. Gameplay by default is first person, but players have the option to play in third person mode.
The Wii Homebrew Applications (such as The Homebrew Channel, Emulators, Games, Media players, etc.), USB Loader GX's NAND emulation feature and DIOS MIOS (Lite) require a FAT32 partition format. You can use a FAT32 SD/SDHC card for that purpose and set your USB hard drive as NTFS or Ext partition format.
Compatible USB storage devices. You can expand the amount of available storage space with external USB storage devices. Nintendo recommends using self-powered hard disk drives, i.e. devices that use an external power supply instead of drawing power through USB. Devices that draw their power from USB ports are known as bus-powered devices, and are not recommended for use with Wii U. For the best results with storage devices, we recommend using a hard drive with its own power supply that connects to the Wii U via the USB port on the console. Please note that you cannot remove/connect a storage device while the power is on.
