Luigi's Mansion is also one of the few Super Mario video games that has an actual storyline other than simply "save the princess."
Luigi is informed that he has won a mansion in a contest -- a contest he didn't even enter. He tells his brother, Mario, to meet him at the mansion. After alerting his brother, Luigi sets off to the mansion himself. When he gets there, he finds that the mansion is haunted by ghosts, and Mario is nowhere to be found. With the help of Professor Elvin Gadd (a researcher of ghosts who lived in a shack near the haunted mansion) and his Poltergeist 3000, Luigi sets off to rescue Mario.Storyline
