The Nintendo Wii has been a smash hit but it's been a little short on titles that actually make use of the onboard wifi connection for online gaming. Hopefully 2008 will change all that and one game aiming to do just that is Wii Chess. Wii Chess uses "loop express", a conversion of the loop chess engine which ranked 3rd in the 2007 World computer chess championship in Amsterdam.
It has 10 levels of difficulty and will allow you to play anyone, anywhere using your wifi and internet connection.
