@phantom1999 the wii u basically have a built in Wii so it can do both! But if youre not going to play any WiiU games then a Wii will be plenty enough for your enjoyment :)
@TweetsByTamzin if you have something similar already, you could try it, but tbh i have not done that myself so maybe @aSaucyDaisy could tell you if it will work? i don't think so but he'll have a better idea
