This game is a Classic in my book, and i purchased it way back when it hit the shelves in Australia, and don't forget you can use the inbuilt voice recog, to do all the ship board things, really nice to play !
Did you want it on the site? maybe a link to it as it is rather huge at 705 mb
Anyway just tought somebody apart from me would enjoy it some more
