I am an avid passionate PC gamer, but I decided to buy a Nintendo Wii to play with my girlfriend and my nephews when they visit us.

Unfortunately I have zero knowledge of console in general, coming from "PC Steam world". I am wondering if also for Wii do exist a digital distribution of game patches (in particular), DLC, etc.

Do I need to connect my Wii directly to internet or is it possible downloading patches with PC and use a memory card or a USB device to transfer them to the Wii?
