I own a copy of this and I have to say that it is much better than I had anticipated. The interface is very swish, and the content is presented in a high level of detail, filling eagar minds with even more useless facts to non-impress friends and family. All in all, a very sound package that really does make you want to read more. If you dont like Star Trek however, then you should probably not buy this, as there is very little else within at all :)
Star Trek Encyclopedia uses a clever star-trek style interface, which is almost exactly like the consoles on the show...if you like that kind of thing. But purple on pink tends to hurt your eyes after a while, and the annoying bleeps and bloops should destroy your ears in no time. As for the software itself? It's packed full of star trek history, pictures, sound files, video clips...but it all tends to become a bit tedious after a while. Not bad, but lacks a bit on the intrest side.
