My arm hurt for maybe the first week of owning the Wii and that was with doing nothing but the Wii Sports thing. Since then I've been fine I think its caused more muscle tone in the arm and it doesn't really bother me anymore not to mention most games the remote is pretty sensitive for very slight movements if you are still doing full swings around your entire body to do something as simple as swing Link's sword or something heres a tip you are doing it wrong. As to KH hoping its for Wii here if its PS3 yes I'll say sorry SE not interested whats wrong with that?
Now Playing : Links Crossbow Training(Wii), Super Mario Galaxy(Wii) FE: Path of Radiance(GC)
