Motion sensor controls is fun
virtual console for retro titles
wireless NEC card built in
only comes with 1 remote + 1 nunchuk, so possible addons would be 2nd controller and nunchuk, component cable for 480p, classic controller for SNES games from virtual console, router or USB dongle if you don't have wireless router access point already
Doesn't have HD (1080i/p)
Overall its a great system... if you are they type of gamer who needs the latest and greatest in graphcis, you'll probably want Xbox or PS3... but if you want a good fun system (with adequate graphics) where the focus is more on gameplay, then the Wii is better suited.
