Before Luigi’s Mansion came out in 2001, Luigi was stuck in Mario’s shadow. Luigi started life as a green-colored palette-swap for Mario in the 1983 arcade game Mario Bros., and that was his role going forward for a long time. If a Mario game had two players, Luigi would be called into action.
That’s why the announcement of Luigi’s Mansion felt like such a big deal. Every major Nintendo home console had launched with a Mario game. Now, the GameCube was going to debut in 2001 alongside a solo Luigi adventure. Finally, the little brother plumber was getting the spotlight.
