The third game featuring Mario, Mario Bros. also brings along his brother Luigi to scour the sewers of New York City to clean up an infestation of turtles, crabs, flies and other pests. Though the mechanics differ from later games, Mario Bros. cemented Mario’s characterization as an Italian-American plumber, his trademark ability to jump on and defeat menacing animal life and his love of giant coins. The game’s multiplayer gameplay, reportedly inspired by Joust, and relatively slow-paced gameplay make it far more approachable than many of Nintendo's previous games.
