Senjo no Demae Mochi (Battlefield: Home Delivery) is a cancelled “poetical pizza delivery game” that was in development by Microsoft Games Studio Japan around 2002 – 2003, planned to be released for the original Xbox. This weird project was conceived by Gabin Ito, who is mostly known for his works on Parappa the Rapper, Um Jammer Lammy and Cubivore. While not many details about Demae Mochi’s gameplay were shared, they described their project as a surreal pizza delivery game. It looked like a strange mix between Katamari Damacy, Crazy Taxi and Yume Nikki.
