My husband and I have owned every Myst game made. Of course over time, we set them aside and moved on to other interests. Years later, I am interested in re-acquiring as many of these games as I can. But reading all these reviews in reference to computer compatibility is a concern. So after much research I found "Good Old Games" website that allows a person to download the games onto their CURRENT computer. These games are formated to work on current operating systems. And you can't beat the cost. (Riven is $5.99). They don't have Exile or Revelations, but just about everything else. Definitely worth checking out, so you don't waste your money trying to download a game that won't run on today's systems.
