Lee Carvallo's Putting Challenge: as the game that Marge bought Bart instead of Bonestorm in an ancient episode of The Simpsons, it's probably one of the most famous fictional video games of all time. Roberto Selavino's Putting Championship is basically the real life manifestation of that game.
Let me be specific: this is a real life video game that you can play.
It costs $1.99AU and you can buy it here.
I love the description of the game on the site:
Six time national putting champion Roberto Selavino came to our video game company with a vision. He wanted to help the young people of the world improve their putting game while as well as provide a thrilling interactive experience.
I am so tempted to buy this right now...
