Mario & Luigi: Paper Jam

Introduction
Mario & Luigi: Paper Jam (called Paper Jam Bros. in Europe and Australia) is a crossover game between the Mario &amp; Luigi series and the Paper Mario series. It was released in North America on January 22, 2016.

Story
The story begins when Luigi accidentally knocks over a book found deep in Peach's Castle, holding the Paper Mario world within. This ultimately releases the paper characters into the Mario & Luigi world, spreading across the Mushroom Kingdom. Bowser and Paper Bowser, despite some disagreements between one another, decide to team up, combine their armies and kidnap their respective Princess Peach. With the aid of Paper Mario, Mario and Luigi must set off to rescue the Paper Toads and both princesses, defeat both Bowsers and send Paper Bowser and his army back to the Paper Mario world.

Trivia

 * This is the first Mario game to feature a crossover of two different Mario series.
 * This game is considered a combination of Mario & Luigi: Dream Team and Paper Mario: Sticker Star.
 * This game has achieved several milestones:
 * This is the fifth Mario & Luigi and Paper Mario game.
 * This is the second Mario & Luigi and Paper Mario game for the Nintendo 3DS.
 * This is the second Mario & Luigi game, where two Bowsers from different times and dimensions appear in the same game. The first was Mario & Luigi: Partners in Time, where Bowser encountered his younger self.
 * This is Petey Piranha's second time in both a Mario & Luigi game and a Paper Mario game. His other appearances were in Mario & Luigi: Partners in Time and Paper Mario: Sticker Star.
 * This is the second time in a Mario & Luigi game where three characters are playable (as Mario, Luigi, and Paper Mario). The first was in Mario & Luigi: Bowser's Inside Story (as Mario, Luigi, and Bowser).
 * This is the 10th Mario RPG.
 * This is the first RPG in the Mario series to feature no save blocks. The player can save whenever he or she wants to.
 * This is the first game in the Mario series where each of the Koopalings are given extended dialogue, rather than their usual grunts and roars.
 * This is also the Koopalings' first time in a Paper Mario game and their second time in a Mario & Luigi game, with their first time in Mario & Luigi: Superstar Saga.
 * This is the second Mario game to feature Petey Piranha as the first major boss. The first time was in Super Mario Sunshine.
 * This is the second time Bowser teams up with himself from a different time and universe. The first time was in Mario & Luigi: Partners in Time, where he teamed up with his younger self.
 * During the point at Gloomy Woods, where King Boo kidnapped the Marios, Luigi is left in a scared state. This first happened in Mario & Luigi: Superstar Saga where Luigi was too afraid to go to Guffawha Ruins, due to being told there is a monster there.
 * Starlow breaks the fourth wall by saying Luigi had a whole year dedicated to him (the Year of Luigi) and mentioning that they are in a RPG.
 * This is the first Mario game since Mario Kart DS where King Boo and King Bob-omb appeared together as bosses. This is also their first appearance in a Mario RPG.
