Announced by publisher Misawa Entertainment but never actually released due to unknown reasons, Christopher Columbus was a shoot'em up that was supposed to ship for Super Famicom in January 1993.

In this bizarre game, you play as the famous explorer as he pilots his flying ship, battling golden dragons, giant tortoises, and wooly mammoths during his quest to find gold, "free people, and restore peace."

An old issue of EGM summed up the game nicely: "While we know Columbus didn't do this, it still makes for an exciting shooter! ... This is a wild game, indeed!" I don't think it's as rad as my Fatal Frame/Uncharted Waters idea, though.
