writes "Announced today on the UbiSoft community boards. Uru Live, the online part of Cyan's PC title Uru: Ages Beyond Myst, will be closing down. They were not able to get enough subscribers (even within the free Beta) to sustain the world. Instead Cyan has refocused its efforts, and will be putting out expansion packs for Uru, the first of which, due out a couple months, will be freely downloadable."
