A friend of mine also bought MK8, but he wants to give me the promo code. (dont worry, i still need to pay him ) I used my MK8 promo code, and got Zelda WindWaker HD. If i want to use the code of my friend, i need to make a new NNID account? And a new Club Nintendo account? If that is true, can i play the free game with my main account?
