Mario & Luigi (known as Mario & Luigi RPG in Japan) is a series of role-playing video games. It is published by Nintendo and was originally developed by AlphaDream prior to their bankruptcy, with Acquire developing the latest title. The series is a spin-off from Nintendo's trademark Super Mario series and stars the titular characters Mario and Luigi. Typically, the stories consist of following the two on a quest to rescue Princess Peach and defeat an antagonist. The games emphasise the simultaneous control of both protagonists, often providing the player with exploration and combat gameplay in the style of typical role-playing video games.

Mario & Luigi began in 2003 on the Game Boy Advance with Mario & Luigi: Superstar Saga. Due to the nature of the text-based story, the personalities of characters (particularly Luigi) were reworked specifically for the game. Several games were then developed by AlphaDream for the Nintendo DS and Nintendo 3DS from 2005 to 2019, with each game including a unique twist on the formula. The Nintendo Switch eventually received Mario & Luigi: Brothership, instead developed by Acquire, released in 2024, in which the art direction switched to a full 3D style. Two titles in the series, Mario & Luigi: Superstar Saga and Mario & Luigi: Bowser's Inside Story, were remade for the Nintendo 3DS with extra content, released in 2017 and 2019, respectively. The latter was the final game in the series to be developed by AlphaDream before they filed for bankruptcy in 2019.

All games were well-received by critics to varying degrees, with the initial three games attaining nominations for various awards (along with the remake of Mario & Luigi: Bowser's Inside Story). Both Mario & Luigi: Superstar Saga and Mario & Luigi: Bowser's Inside Story received "universal acclaim", according to review aggregation website Metacritic. The former has been considered to be one of the best Nintendo GBA games of all time, and the latter one of the best Nintendo DS games of all time.

Gameplay The gameplay of the Mario & Luigi series consists of typical role-playing elements, and primarily differs from most other role-playing video games (RPGs) through its focus on controlling Mario and Luigi simultaneously. During exploration and interaction with the world, known as the overworld, the player controls Mario's movement, with Luigi following closely. Mario and Luigi's other actions are controlled individually with the A (Mario) and B (Luigi) buttons, respectively, in both the overworld and battle sections. These controls are used to explore the overworld to solve puzzles and find collectibles using various special moves that often have Mario and Luigi working together.

Like many other RPG series, the Mario & Luigi series contains a traditional turn-based battle system. The games have a mechanic similar to the Paper Mario franchise, in which attacks are empowered by precisely timing inputs based on the attack's animation, including Mario and Luigi's signature jumps as well as hammer attacks. Unique to the series is the use of real-time commands while an enemy is attacking, rewarding the player's good timing with the ability to completely avoid an attack or even do damage to the enemy instead of getting hit and contrasting the usual turn-based combat. Some titles in the series feature additional playable characters alongside Mario and Luigi including Baby Mario and Baby Luigi in Mario & Luigi: Partners in Time, Bowser in Mario & Luigi: Bowser’s Inside Story, and Paper Mario in Mario & Luigi: Paper Jam.

Games

Main games

Mario & Luigi: Superstar Saga was released on the Game Boy Advance in 2003. It follows the journey of Mario and Luigi as they attempt to track down Cackletta, who stole the voice of Princess Peach. It established the gameplay formula that would be iterated on throughout the series, including the (often simultaneous) control of multiple characters, puzzles, and dodging enemy attacks during turn-based combat through well-timed inputs. Mario & Luigi: Partners in Time was the first Nintendo DS title and released in 2005. The introduction of Baby Mario and Baby Luigi doubles the number of simultaneously playable characters to four, with the option to separate into pairs. Set in the Mushroom Kingdom, the plot incorporates time-travel elements, as Mario and Luigi must rescue Princess Peach after she is sent back in time by the alien "Shroobs". Mario & Luigi: Bowser's Inside Story released for the Nintendo DS in 2009. Antagonist Fawful causes Bowser to inhale several Mushroom Kingdom inhabitants, including Mario, Luigi, and Princess Peach. It partially follows Mario and Luigi, sometimes through two-dimensional gameplay taking place inside of Bowser, with other sections instead following Bowser's perspective via three-dimensional gameplay sections. Mario & Luigi: Dream Team was the first Nintendo 3DS game and released in 2013. Alternating between the real world (within Pi'illo Island) and the dream world, Mario pursues damsel-in-distress Princess Peach with frequent help from Dreamy Luigi. In the dream world, the touch screen is utilised to tug on Luigi's moustache as he sleeps, in order to control various aspects of the world such as palm tree branches and the flow of time. Mario & Luigi: Paper Jam was released in 2015 on the Nintendo 3DS. Princess Peach and her paper counterpart are captured by Bowser and Paper Bowser, so Paper Mario joins Mario and Luigi to save them. Controlling the three characters simultaneously, the player may use "trio combos" in battle while acquiring boosts through "battle-cards". Some puzzles in the overworld take the form of minigames. Mario & Luigi: Brothership released in 2024 for the Nintendo Switch. It follows Mario and Luigi's mission to reconnect the islands of Concordia, accessed by sailing a moving island. It introduces mechanics such as "Luigi logic", where for the first time in the series, Luigi may act independently from the player during gameplay, and "battle plugs" which provide boosts in combat with a limited number of uses before needing to be recharged.

Remakes

Mario & Luigi: Superstar Saga + Bowser's Minions is a Nintendo 3DS remake of Mario & Luigi: Superstar Saga and released in 2017. It adds the side mode Minion Quest: The Search for Bowser, involving forming a horde of troops to battle against a horde of enemies, with three types of troops, strong and weak to one another in a rock-paper-scissors fashion. Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey is a Nintendo 3DS remake of Mario & Luigi: Bowser's Inside Story and was released in 2019. The additional side mode Bowser Jr.'s Journey is present, playing similarly to Minion Quest, with additional special moves.

Recurring characters Fawful known in Japan as Gerakobits, is a recurring antagonist. The character is considered to be "insane", and speaks in a chaotic manner. He served as the secondary antagonist of Superstar Saga, and the main antagonist of Bowser's Inside Story. He was also the main antagonist of Bowser’s Minions, in which he brainwashed all of Bowser's minions, and became Captain Goomba’s archenemy.

He was created by Masanori Sato, who worked as the illustrator for Mario & Luigi: Superstar Saga, the first game in the Mario & Luigi series. Fawful's localized Japanese name, Gerakobits, is derived from geragera, the Japanese onomatopoeia for a scornful laugh. Because Fawful was not based on any existing characters in the Mario series, the Nintendo Treehouse, which is responsible for localizing games for North American audiences, had more creative freedom in writing for the character. Bill Trinen and Nate Bihldorff, employees of the Treehouse, wrote the English dialogue for Fawful through the exchange of notes. Rather than sticking close to the Japanese script, where Fawful simply adds "Fururururu!" to the end of every line, Trinen and Bihldorff intended to make Fawful as "wacky" and "zany" as possible in the Western release. Thus, in English versions of the games, all of Fawful's dialogue consists of broken English and word salads, along with his catchphrase, "I have fury!".

Popple or the Shadow Thief as he calls himself, is a recurring antagonist. He first appears as a major antagonist in Mario & Luigi: Superstar Saga where he is fought four times throughout the game, and fights alongside an amnesiac Bowser, going under the alias "Rookie", for the first two battles. However, after Popple and Bowser get separated, Popple recruits Birdo to fight alongside him for the fourth battle; following his defeat and unseen arrest, he is forced to do community service in Little Fungi Town. Popple later returns in Mario & Luigi: Dream Team as a minor antagonist. He is first seen robbing Pi'illoper’s house and encounters the Bros., though he does not seem to remember them. Later on, he works with the Bros. to battle a Wiggler named Wiggly, but he turns against them after Wiggly is defeated. In his English dialogue for Superstar Saga, Popple's manner of speech parodies the "wise guy" dialect used by actor Edward G. Robinson in gangster films such as Little Caesar, often interjecting "see" at the ends of his sentences.

Development 2000–2003: AlphaDream founding, conception, and first game AlphaDream was founded in January 2000 by Tetsuo Mizuno, Square's former president. Square had previously developed Super Mario RPG, the first role-playing game (RPG) starring characters from the Mario series. After a number of smaller games, Mario & Luigi: Superstar Saga was AlphaDream's first game to be released outside of Japan on November 17, 2003.

The Mario & Luigi series took inspiration from Super Mario RPG when it came to turn-based combat, which AlphaDream producer Yoshihiko Maekawa co-directed. In an interview, he remarked that one inspiration for Super Mario RPG was a children's toy in Japan where buttons had to be pressed in time with the music. From there, he conceptualized turn-based mechanics that blended real-time action with general RPG gameplay by allowing the player to make timed button presses to be more successful in their attacks. AlphaDream iterated on this timed button-pressing concept for Mario & Luigi: Superstar Saga by letting the player dodge enemy attacks entirely.

When it came to characters in the Mario franchise at the time, they were generally underdeveloped personality-wise. Since Mario & Luigi mainly employs a text-based story, and would see the duo interacting with many different characters across the storyline, AlphaDream wished to approach the characters from scratch. With Nintendo's approval and support, characters such as Luigi were reworked by the team, attempting to stay true to what originally made them charming to fans.

2004–2009: Nintendo DS era Nintendo revealed Mario & Luigi: Partners in Time (then called Mario & Luigi 2) at E3 2005, where a playable demonstration of the game was available. The demo consisted of three levels, each accompanied by a tutorial to guide the player. Each level had a different objective and represented the characters' abilities in the game, such as the use of the hammer. Between the game's unveiling at E3 and its release, Nintendo of America revealed details of the game relating to Partners in Times plot and gameplay, as well as the fact that it would be compatible with the "Rumble Pak" feature. Partners in Time was first released in North America on November 28, 2005. Mario & Luigi: Bowser's Inside Story was revealed to be in development in October 2008 in Japan at Nintendo's Tokyo Press Event under the temporary title Mario & Luigi 3. The North America and Europe release was announced at the E3 2009 event and it released on September 15, 2009.
