I had the Alan Dean Foster novelization, the action figures, and I think one of the Whitman jigsaw puzzles, but I didn’t know about the board game. Simple spin, move, and draw affair: Each player has to get his/her Perseus all the magical equipment he needs to defeat Medusa and the Kraken.
The cover art is a copy of the movie poster by Dan Goozee (note Bubo had to be moved so as not to be obscured by the title letters), but the interior and card art is original. I wish I had some better close-ups. I think Whitman used the same artist for the puzzles, which are hard to find.
