I have this game if abandonia wants it. I found this document signed by the makers of the game. It states that in 1998 they marked it as *ABANDONED - NO STATEMENT OF USE FILED*.....im not sure if that means it really is abandoned but ive done tones of looking around and i cant find any legit place this game is being sold by The McGraw-Hill Company.

This is a great edutainment game and well worth a nostalgic gamer/parents time to check it out
