The reason I said that about the version, is because if it says the word 'hybrid' on the disk or on the folder, then this one is possibly the new one. I say this because on the web site, they are calling their disk a 'hybrid'. This was never on any of the other versions. Mine is the Win only version. They also produced a Mac only version. Perhaps later they produced a win/mac version, but not for GTE. By that time the publisher was gone. They only published Timelapse and Titanic for them, both games very popular, but not money makers I guess. This same type of thing happened with the beautiful puzzle games, Karma, and Jewels of the Oracle.
