Banjo-Kazooie: Grunty's Revenge

Banjo-Kazooie: Grunty's Revenge is a 2003 platform game by Rare for Nintendo's Game Boy Advance (GBA). It is the third instalment in the Banjo series, and is a spinoff that takes place between the events of the Nintendo 64 (N64) games Banjo-Kazooie (1998) and Banjo-Tooie (2000). In Grunty's Revenge, the evil witch Gruntilda travels back in time to prevent the events of Banjo-Kazooie from happening, and the bear Banjo and his bird friend Kazooie set out to stop her. Grunty's Revenge retains the focus on collecting items and most of the other game mechanics from its predecessors, but is presented in 2D rather than 3D. Aside from the main game, players can also access minigames such as fishing and target shooting.

Rare began to plan Grunty's Revenge in August 1999. At this time, it was titled Grunty's Curse and was planned for release on the Game Boy Color, and featured a different plot. Rare was working on the game's sprites when production halted in late 1999. However, it was revived after Nintendo released the GBA. Nintendo rival Microsoft's purchase of Rare in 2002 did not affect their plans to develop the game; Microsoft negotiated a deal with THQ to publish Grunty's Revenge alongside Rare's other GBA projects. The game was released for the GBA in September 2003 and a port for mobile phones was released in June 2005. Grunty's Revenge received average reviews; although its visual style and gameplay were praised and favourably compared to those of the N64 games, its low difficulty and story were criticised.

Gameplay
Like its Nintendo 64 (N64) predecessors Banjo-Kazooie (1998) and Banjo-Tooie (2000), Banjo-Kazooie: Grunty's Revenge is an adventure platformer with a strong emphasis on collecting items. The player must control the player characters, the bear Banjo and his bird friend Kazooie, through several levels. The story takes place between the events of the N64 Banjo games and employs time travel as a key plot device. In the story, the evil witch and antagonist of the previous games, Gruntilda, kidnaps Kazooie and goes back in time to prevent her from meeting Banjo, thus preventing the events of Banjo-Kazooie. The shaman Mumbo Jumbo sends Banjo back in time to stop Gruntilda. At the start of the game, the player controls just Banjo, who can walk, jump, crouch, and attack enemies with his backpack. Collecting golden musical notes scattered around levels will enable Banjo to purchase three additional abilities from a mole named Bozzeye. Eventually, Banjo rescues Kazooie, who rides in his backpack for the remainder of the game. With Kazooie, the player can purchase seven new abilities, such as temporary flight. While Grunty's Revenge's game mechanics are largely the same as those from the N64 games, it is presented in 2D from an overhead perspective with pre-rendered graphics, rather than the 3D presentation of its predecessors.

There are five levels (called worlds), which are accessed from the overworld Spiral Mountain. In each world, players must collect items scattered around the environments. These include the musical notes; puzzle pieces called Jiggies, which unlock levels and progress players through the game; empty honeycombs, which extend Banjo's energy bar; and lost birds called Jinjos, which will give the player a Jiggy when every one in a level is found. Progress is tracked on a statistics screen showing maps of each location and collected items. Other collectibles include totems and coins; overall, there are more than 750 collectibles. If Banjo gives totems to Mumbo Jumbo, he will gain power-ups, such as the abilities to turn into a tank or a mouse. Some areas in levels are inaccessible unless Banjo buys new abilities or obtains power-ups. Every level features an "arena style" boss fight with Gruntilda or her minion, Klungo. The final boss fight is a game show-style quiz testing the player's knowledge of the game mechanics. Aside from the platforming, some levels feature minigames, such as fishing, racing, and target shooting. The closing credits features a minigame where the player can earn tokens, which can be used to purchase and replay unlocked ones in an arcade cabinet hidden in one of the levels.

Development
Grunty's Revenge was developed by Rare for the Game Boy Advance (GBA), a handheld game console by Nintendo. Production lasted four years and began in August 1999, a year before the release of Banjo-Tooie and when Rare was still a second-party developer for Nintendo. Although it was developed and released on the GBA, Grunty's Revenge was initially planned for the system's predecessor, the Game Boy Color. It was originally titled Banjo-Kazooie: Grunty's Curse and was conceptualised by a small team. Grunty's Curse's story was different: it was set in an parallel universe, did not involve time travel, and would have taken place several years after the events of Banjo-Kazooie. In the story of Grunty's Curse, Gruntilda curses Bottles the mole and Mumbo Jumbo, and kidnaps Kazooie and turns her into a monster; to save them, Banjo must find several magic ingredients. As he has not adventured in a long time, Banjo sets out to be retrained by Bottles' father Grampa Mole (who became Bozzeye in the final version). The original plot is referenced as an in-joke in the final game; when Banjo finds Kazooie, he says he is surprised Gruntilda did not turn her into a monster. Grunty's Curse was to feature more levels and power-ups than Grunty's Revenge. Rare was working on the game's sprites when production halted in late 1999.

Production restarted after Nintendo released the GBA. Rare retitled the game Grunty's Revenge and changed the plot so it would fit better in the series' universe. It was announced and showcased along with Rare's other GBA games they were working on at the time at E3 2001. Development continued even after Rare was acquired by Nintendo rival Microsoft, which does not make handheld game consoles, in 2002. Grunty's Revenge was nearly complete at the time, but Rare chose to continue to fine-tune it during their transition to a first-party developer. It also gave them time to implement 3D computer graphics. A multiplayer mode using the GBA's Game Link Cable was planned but cut. On 11 August 2003, Microsoft announced it was collaborating with THQ to publish Rare's GBA projects, including Grunty's Revenge, a remake of Sabre Wulf (2004), Banjo spinoff Banjo-Pilot (2005), and It's Mr. Pants (2005). The game was released in North America on 12 September 2003 and in Europe on 24 October 2003. It was Rare's first game after the Microsoft buyout and their first game in over 10 years that they or Nintendo did not publish. A port for mobile phones was released by InFusio in June 2005. Another mobile game comprising the minigames, Grunty's Revenge Missions, was released around the same time.

Reception
According to Metacritic, a video game review aggregator, Grunty's Revenge received "mixed or average reviews". Opinions regarding the game as a whole differed. Some reviewers, such as those from IGN, GameZone, GameSpy, and retrospectively Nintendo Life, applauded it as a splendid effort to bring Banjo-Kazooie to a handheld device. Nintendo Life went as far as to call it the closest thing to a pure Banjo experience outside the originals. Others, such as those from GameSpot and Eurogamer, argued it did not stand out from other GBA games; Eurogamer also said it did not compare well to GBA platformers like Super Mario Bros. 3 (2003). Both also believed its shortcomings ruined the experience and only recommended it to fans of the series or Rare's games. Reviewers generally agreed the story was subpar. IGN called it "half-baked", weak, and poorly written; they felt it did not use the time travel aspect well and should have had more in-jokes and references to the two previous Banjo-Kazooie games. Others described it as too confusing, lame, and "ludicrous". However, Jeuxvideo.com praised its offbeat, humorous tone.

Reviewers were more generous towards its gameplay, with many favourably comparing it to that of the original games.  GameZone and GameSpy thought the series' gameplay transitioned well from the N64 to the GBA,  with GameSpy writing Grunty's Revenge did not merely mimic the N64 games and, unlike other platformers, was never repetitive. Jeuxvideo.com found the environments vast, IGN said the gameplay was "just as deep and extensive" as it was on the N64, and Nintendo Life believed it managed to "cram all of [Banjo's] platforming goodness into a cartridge with a fraction of the capacity". The minigames were also praised as an addictive and fun diversion that added depth to the main game. On the negative side, reviewers were disappointed the promised multiplayer mode was absent;  IGN and GameZone agreed the racing minigame would have worked well in a multiplayer mode. Other complaints were levied against the overhead view—which was said to make it difficult to judge heights —and GameSpot believed the best aspects of the game were "overshadowed by its Sisyphean focus on item collecting."

The visuals and sound were praised. Many reviewers believed the visuals were colourful and well-animated, and were impressed by their faithfulness to the N64 games. They wrote Rare did a great job recreating the world of Banjo-Kazooie in 2D.  Nintendo Life favourably compared the pre-rendered graphics to Donkey Kong Country and GameZone called them vibrant and detailed. Eurogamer said that while it was not the GBA's prettiest game, most of Grunty's Revenge's visuals were well-done, although they thought the backgrounds were lacklustre. Jeuxvideo.com and Pocket Gamer were more critical; Jeuxvideo.com felt the colours were odd and the text was hard to read, and Pocket Gamer argued the art style was too cute. Reviewers were surprised by how similar the audio was to the N64 games. IGN called the music catchy and the sound as a whole impressive, and GameZone appreciated that Rare brought "Banjo’s hilarious and indescribable jibber-jabber" back.

The low difficulty and short length were primary aspects of criticism. Reviewers estimated that the game could be completed within a matter of hours, and also felt it lacked replay value. GameSpot, for example, believed there were not many areas where players could slow down and interact with the environment, and Eurogamer called the game boring. Boss fights were singled out as one of the game's biggest failings; they were criticised for their uninspired nature and lack of challenge, although IGN and Nintendo Life considered the final boss a highlight. Pocket Gamer also wrote it was easy to get lost in the game world.
