Yes, this is a completely real, playable game based on F. Scott Fitzgerald's The Great Gatsby. Charlie Hoey and Pete Smith made this wonderful gem. Just click on the link and follow the instructions.
I may be the outlier so far, but I loved this book. I just finished reading it, and I really got into it. It's a story of foolishness and a struggle to maintain power over someone you love. I can understand why people would dislike it, though.
Same as Catcher in The Rye. Not sure why some books were actually popular.
