I'm about to finaly get a Wii in the next 2 weeks. I want to know what accessories is a must have. I already know that I'm getting another control and nunchuck so me and my brother can play together. And I know that I have to get a memory card if I plan on saving my games, right? Or is the memory card for when you download the older games? And is it a special kind of memory card or can I just buy a regular SD card? I already have a wireless router so I should be good as far as getting online and playing people. is there anything else I'm missing?
