URU

Uru : Ages of Myst

According to Wikipedia, published in 2003 and number four of the series.

Installed on our branded Dell, which has ATI Radeon graphics cards. The game became deeply unstable. I checked out the internet and a patch has been issued, but it is suggested that not all installs require it. ubi.com's community forum site has published advice on when to install the patch. The mentioning of the ATI Radeon technology and the instability of the game led me to decide to install the patch.

UHS have a URU walkthrough, and Ubusoft, the publishers, point at http://www.mystworlds.com/us/, a news and community site.

I have bookmarked a couple of resources, at delicious, tagged "uru" to help me make my mind up and play the game.
