The demo of Introversion Software's (Previously they did Uplink) Darwinia has been released and frankly it is a must play. Only way to describe it is a little of a mixture of Black and White and a typical RTS with Tron thrown in for good measure.
OK so its almost impossible to describe but its damn worth playing if you like PC games dammit!
