Mario + Rabbids Sparks of Hope

Mario + Rabbids Sparks of Hope is a Nintendo Switch game released on October 20, 2022. It is the second game in the Mario + Rabbids series, and the sequel to Mario + Rabbids Kingdom Battle. Like its predecessor, the game is a crossover featuring characters from the Super Mario franchise and Ubisoft's  series, and sees the return of characters from the previous game in addition to introducing new ones such as Rabbid versions of Rosalina and Lumas named Sparks. The game contains nine playable characters with a team of three allies like its predecessor. The game's story revolves around the cast venturing through space and traveling to different planets to rescue the Sparks. Also similar to its predecessor, the game was leaked ahead of its official announcement, on Nintendo's official website hours prior to the Ubisoft Forward 2021 broadcast. On March 2, 2023, a demo was added to the Nintendo eShop.

While Nintendo published the game in Japan like it did its predecessor, Ubisoft took publishing duties for South Korea, Hong Kong, and Taiwan over from Nintendo.

Plot
Sometime after the events of the previous game, Mario and his friends are enjoying a relaxing day on Princess Peach's Castle grounds, before a Spark abruptly falls from the sky. It turns out that he was fleeing from a gigantic manta ray, who proceeds to spread Darkmess, a type of dark matter, across the land and kidnaps Rabbid Peach. Mario and Beep-0 leap in to save her, before the two manage to hold off waves of enemies. Soon enough, an entity named Cursa arrives to confront them, but the heroes are rescued by their friends in their new ship, the WM ARC, where they are introduced to the onboard AI, JEANIE. JEANIE explains Cursa's plot to corrupt the whole galaxy with its Darkmess, as well as the existence of the Sparks, and the heroes set out on their interstellar journey.

During their travels, the party traverses five different Darkmess-contaminated planets and cleanses them from within; they bring sunlight back to Beacon Beach, stop a blizzard in Pristine Peaks, return the forest's colors in Palette Prime, repair the trains and foliage in Terra Flora, and fix the windmill in Barrendale Mesa. Along the way, they also recruit new teammates: the mysterious Edge, the deadpan Rabbid Rosalina who idolizes the real Rosalina, and even Bowser, who is looking to reclaim his brainwashed Koopa Troop. Meanwhile, Cursa sends out the Spark Hunters—Midnite, Bedrock, and Daphne—to help round up the remaining Sparks, only for the heroes to defeat them too.

Eventually, the crew manages to corner Cursa, who is briefly incapacitated when Rosalina shows herself, revealing that she has been kidnapped and absorbed by the creature. She is captured again, but not before giving the heroes a projection crystal and opening a portal to help them escape. Through the crystal, the heroes are able to learn the full story: created from the last remaining fragment of the Megabug, Cursa escaped into space and was able to gain both sentience and power, and now wants to consume the Sparks' energy and take over the galaxy, spreading Darkmess across its planets. During its conquest, it managed to conquer the Comet Observatory and even possess Rosalina after being drawn in by the joy of the Lumas and Rabbids. During its fight with Rosalina, one of her attacks managed to create the Sparks by fusing the latter two together. Cursa then proceeded to form an army of Rabbids to take over the galaxies, steal Bowser's army, and create the Spark Hunters to help it harness more power.

Upon arrival at Cursa's stronghold, the heroes fight Darkmess versions of both Bowser and Edge, before the real Edge confesses that she herself was once a Spark Hunter, although she turned on Cursa after gaining enough free will to see how evil it was, and has since vowed to save as many Sparks as she can. The group manages to thwart Cursa by destroying its arms, causing it to release every last Spark she consumed as well as Rosalina. After three rounds of helping the latter charge up her magic, the heroes shoot their weapons, with Rosalina forming them into a giant arrow, thus defeating Cursa for good, saving the galaxy. Back in the Mushroom Kingdom, Rosalina congratulates everyone on their success before offering her Rabbid counterpart a chance to live with her. Rabbid Rosalina declines, stating that she already has a family in her teammates. Edge decides to stay with the team too. Before her departure, Rosalina even praises Bowser for his contributions, only for him to insist that he is still enemies with them.

A post-credits scene shows Beep-0 having a friendly conversation with JEANIE, who has somehow developed emotions over the course of the journey.

Gameplay
Like its predecessor, Mario + Rabbids Sparks of Hope is a strategy turn-based game. Exploring the overworld is also similar, but more open-world rather than linear. Quests are present while exploring the planets, and can be done once encountered by the player.

Combat has some real-time elements to it, such as characters gliding in the air and Stone Masks "breathing" wind every few seconds. Heroes can move as much as they want until they use their weapon, and can only perform two actions per turn. Each hero has one weapon and Technique, unlike the first game where they had two for each. Sparks add active and passive abilities to each hero, and can be changed between battles. One Spark is available for each hero at the start, but two can be equipped starting at the Pristine Peaks battle Icy Breath of Winter.

In addition to the real-time, Sparks of Hope adds RPG elements by having characters gain experience and leveling up, becoming stronger. Battles and quests award heroes XP, and HP and attack power is increased after leveling up. Skill Prisms are also obtained by leveling up.

Main game
There are nine playable characters in the main game. Of the eight playable characters from the previous game's main campaign, six of them return in this game, as Yoshi and Rabbid Yoshi are stated to be on a vacation and do not return. Likewise, Donkey Kong and Rabbid Cranky from the Donkey Kong Adventure campaign are also absent. Three new playable characters are introduced in the main game, including Bowser, who was a boss in the previous game. Like the previous game, the player creates a party to travel the worlds and fight in battles, though this time, Mario is not required to be in the party at all times and the party does not require at least one Rabbid. Until Edge joins the team, only two party members will be active, at which point three party members will be active for the rest of the game, although there are certain boss battles that use four with one of the nine characters being required to use.

The following descriptions are taken from the game's official website and from in-game character profiles.

Memories
Memories are collectible pieces of information recorded by JEANIE of various characters, enemies, and locations. They can be obtained by examining Probes, purchasing them from SALESBOT 9.99+TX with Planet Coins, and clearing certain enemy battles.

Difficulty settings
Unlike the previous game, Mario + Rabbids Sparks of Hope has a difficulty option in the settings. It allows the player to change their difficulty even after deciding it after the prologue. This changes the enemies' strength and health, making it easier or harder for the player to defeat them; alters whether the Heroes' health is restored after each battle or upon leveling up; and whether the Heroes' Skill Trees are automatically customized. There are three difficulty settings—Relaxed, Average, and Demanding—as well as a Custom setting that allows the player to customize the paramaters in each difficulty setting.

Enemy Threat
This menu option alters how much damage enemies inflict on the Heroes and their HP, from three settings: Low, Medium, and High. Medium is the default setting. Low reduces enemy HP and makes enemies inflict less damage, and High increases enemy HP and makes enemies inflict more damage. The difficulty setting the player chooses for the game also determines the Enemy Threat setting, but can be individually changed at any time.

Hero Health Management
This menu option allows the player to choose whether the Heroes' HP is automatically restored partially after winning a battle, upon leveling up, or not at all. The difficulty setting the player chooses for the game also determines the Hero Health Management setting, but can be individually changed at any time.

Invulnerability
This option allows the player to make the Heroes invulnerable or vulnerable to damage—regardless of difficulty setting selected—by selecting On or Off, respectively. The Heroes are still vulnerable to Super Effects and negative effects, however.

Mario + Rabbids Sparks of Hope was released in three editions: the Standard Edition, which only includes the base game; the Cosmic Edition, which includes the base game and the Galactic Prestige Pack; and the Gold Edition, which includes the base game and the Season Pass (referred to as the Adventure Pack in Japanese) featuring downloadable content packs (which contain additional story, characters, quests, and battles).
