Can I sue Nintendo?

So over the weekend housemate bought a communal TV (pretty pretty LCD) for the loungeroom and as such our 360 and Wii are now attached.
Now, I’ve never played a Wii before but I imagined they were much fun… which it is, however after playing many a match of Wii Sports Tennis my arm wants to fall off ๐Ÿ˜› I can barely lift it… seriously, work was so hard yesterday, even just writing.
So I wonder, can I sue Nintendo… I wonder if anyone has tried? I mean people sue fast food places why not this? I wonder what my luck would be.
On a last Wii note, I’m considering buying Wii Fit… anyone own it? Is it decent?

Also, Happy New Year to everyone! I, for one, am very VERY pleased 2008 is done and over! What a terrible terrible year! Here’s hoping 2009 is a year for pleasant surprises and wonderful opportunities ๐Ÿ™‚
