Well, I guess it depends on how OLD you are

Funny thing is, my neighbor, who's mid 40's, got his son a Wii early this year. Fast-Forward, he had to go to the doctor as he was having a lot of pain, and had no idea what was troubling him. Turns out, he was pulling muscles while playing Wii SPorts Tennis. Hes from Lebanon, and had never played a video game before. He said he was "really going at it, every nite"--tennis, that is.
Anyway, I just got my son a Wii this Christmas, and must say its a ton of fun. I got Guitar Hero(my wife wont stop playing that), Mario Galaxy, but, we've been playing the Sport game disc that comes with it. Bowling, and tennis are really cool, especially watching my 9 and 7 year olds playing tennis together and almost knocking each other out swining their Wimotes.
I hooked up the ethernet tonight, and purchased classics like SuperMetroid, Kid Icarus, and Super Mario 2--all of which Ive played on my NES a million times, especially Metroid/SuperMetroid. Cant wait til they go to sleep so I can play those! So much for my old NES cartridges.
Now, if only my copy of Prologue would arrive from Play-Asia, supposedly shipped the 13th. Grrrrrr
