The BBC released an online version for the 30th Anniversary of the Hitchhikers Guide with some additional graphics if anyone would like some nostalgia [1].

I don't know anyone who finished that game. It could be very frustrating. I was very pleased just to get the babel fish. Since then I have read the walk through and I doubt could have ever completed it without help. [2] (spoilers!)
