Pokémon Diamond and Pearl

and are role-playing video games developed by Game Freak and published by The Pokémon Company and Nintendo for the Nintendo DS in 2006. They are the first installments in the fourth generation of the ''Pokémon'' video game series. They were first released in Japan on September 28, 2006, and released in North America, Australia, and Europe in 2007. '' Pokémon Platinum'', a third version, was released two years later in each region. Remakes titled ''Pokémon Brilliant Diamond'' and ''Shining Pearl'' were released for the Nintendo Switch worldwide on November 19, 2021. An interquel, '' Pokémon Legends: Arceus'', was released for the Nintendo Switch on January 28, 2022.

Like previous ''Pokémon'' games, ''Diamond'' and ''Pearl'' chronicle the adventures of a young Pokémon Trainer as they train and battle Pokémon while also thwarting the schemes of a criminal organization called Team Galactic. The games added many new features, such as Internet play over the Nintendo Wi-Fi Connection, changes to battle mechanics and Pokémon Contests, along with the addition of 107 new Pokémon. The games are independent of each other but feature largely the same plot, and while both can be played separately, it is necessary to trade between them in order to complete the games' Pokédex.

Development of ''Diamond'' and ''Pearl'' was announced at a Nintendo press conference in the fourth calendar quarter of 2004. The games were designed with features of the Nintendo DS in mind. It was forecasted to be released in Japan in 2005, but ultimately shipped in 2006, the 10th anniversary year of the franchise. In promotion of the games, Nintendo sold a limited-edition Nintendo DS Lite in Japan, and held a release party celebrating their North American release.

The games received generally favorable reviews. Most critics praised the addition of Wi-Fi features and graphics, and felt that the gameplay, though it had not received much updating from previous games, was still engaging. The games enjoyed more commercial success than their Game Boy Advance predecessors: with around 18 million units sold worldwide, ''Diamond'' and ''Pearl'' have sold over 2 million more units than their predecessors ''Pokémon Ruby'' and ''Sapphire'' and almost 6 million more units than ''Pokémon FireRed'' and ''LeafGreen'', while also outselling their successors, ''Pokémon Black'' and ''White'', by over 2 million copies. The games are among the most successful ''Pokémon'' games of all time.

Gameplay

''Pokémon Diamond'' and ''Pearl'' are role-playing video games with adventure elements. The basic mechanics of the games are largely the same as their predecessors. As with all ''Pokémon'' games for handheld consoles, the gameplay is in a third-person overhead perspective, and consists of three basic screens: a field map, in which the player navigates the main character; a battle screen; and the menu, in which the player configures their party, items, or gameplay settings. Players begin the game with no Pokémon or Poké Balls but are given the choice of three Pokémon as a part of the storyline. Once Poké Balls are obtained, the player can capture more Pokémon. Players can use their Pokémon to deal damage to other Pokémon in battle. Whenever the player encounters a wild Pokémon or is challenged by a trainer to a battle, the screen switches to a turn-based battle screen where the Pokémon fight. During the battle, the player may use a move, use an item, switch the active Pokémon, or flee. Fleeing is not an option during battles against trainers. All Pokémon have hit points (HP); whenever a Pokémon's HP is reduced to zero, it faints and cannot battle unless revived at a Pokémon Center or with an item. If the player's Pokémon defeats the opposing Pokémon by causing it to faint, it receives experience points. After accumulating enough experience points, it will level up; most Pokémon evolve into a new species of Pokémon whenever they reach a certain level. Pokémon's stats also increase every time it levels up, and they will also learn new moves at certain levels as well. If a Pokémon is prevented from evolving it will learn new moves faster.

Apart from battling, capturing Pokémon returns as a critical component of ''Pokémon'' gameplay. Although other trainers' Pokémon cannot be captured, the player can use different kinds of Poké Balls on a wild Pokémon during battle. A successful capture adds the Pokémon to the player's active party or stores it if the player already has a maximum of six Pokémon in their party. Factors in the success rate of capture include the HP of the target Pokémon and the strength of the Poké Ball used; the lower the target's HP and the stronger the Poké Ball, the higher the success rate of capture is. Also, inflicting certain status effects such as sleep or paralysis adds a multiplier to the capture rate, making it easier to capture wild Pokémon. Each species has a capture rate of its own as well.

New features

As with other generations of ''Pokémon'' games, ''Diamond'' and ''Pearl'' retain the basic gameplay of their predecessors while introducing additional new features. The day-night cycle makes a return and has increased from three times of day in ''Gold'' and ''Silver'' to five time periods in ''Diamond'' and ''Pearl'': morning, day, afternoon, evening, and night.In the game mechanics that depend on the time of day, afternoon counts as day, and evening counts as night. ''Diamond'' and ''Pearl'' also introduce several changes to battle mechanics. In previous generations, Pokémon moves were classified as "physical" or "special" based on their type; for example, all Fire-type moves were special and all Ground-type moves were physical. In ''Diamond'' and ''Pearl'', however, moves are categorized into three groups. Attacks that make physical contact with the opponent are "physical", attacks that do not make physical contact are "special", and moves that do not deal damage are classified as "status".

Some of the games' new features capitalize on the Nintendo DS's features. The Pokétch, a simulated smartwatch, resides on the DS's bottom screen and hosts various applications including a clock, calculator, map, counter, and a drawing pad. These applications are obtained throughout the game. Beneath Sinnoh's surface is the Underground, a large area used for wireless multiplayer gaming;Via DS wireless communication, not Nintendo Wi-Fi Connection in it, players can create and decorate secret bases, first featured in ''Pokémon Ruby'' and ''Sapphire'', and participate in minigames. The items mined in the Underground can then be transferred into the player's bag in the main game. ''Diamond'' and ''Pearl'' also employ support for the Nintendo Wi-Fi Connection (since discontinued), allowing players to communicate through voice chat, trade, and battle online. The main system for trade is the Global Trade Station, which allows players to trade with people around the world. Players can search for any Pokémon that they have seen in the game and can offer their own; if another player is offering the requested Pokémon and is looking for the offered Pokémon, the trade occurs immediately. A trade does not have to be instant; an offer can be left for other players to browse and complete, even while the player is offline. Certain species of Pokémon traded internationally will have a Pokédex entry in the language of the game it originated from. According to ''Pokémon'' art director Ken Sugimori, the Global Trade Station was the new feature he was most pleased with.

Pokémon Contests are events in which the player's Pokémon compete in a show to win ribbons and, in ''Diamond'' and ''Pearl'', they consist of three stages, two more than the Contests of the Game Boy Advance games. In the Visual Competition stage, players use the Nintendo DS's touchscreen to place accessories on their Pokémon to boost a particular trait, such as "Cool" or "Cute", and earn points. In the Dance Competition stage, the player must tap buttons on the touchscreen in rhythm with the music. The final stage, Acting Competition, is similar to Pokémon Contests of the Game Boy Advance games; Pokémon use their moves to appeal to the judges and crowd. Like Pokéblocks in the third-generation games, baked goods called Poffins can be made from berries and fed to Pokémon to boost a particular trait, and therefore, the likelihood of success in a relevant Contest.

Connectivity to other devices

In addition to compatibility with each other, ''Diamond'' and ''Pearl'' offer compatibility with the third generation ''Pokémon'' games, ''Pokémon Ruby'' and ''Sapphire'', ''Emerald'', and ''FireRed'' and ''LeafGreen''. They are also compatible with ''Pokémon Ranger'' and '' Pokémon Battle Revolution''. After earning the National Pokédex in ''Diamond'' and ''Pearl'', the player can "Migrate" Pokémon from the Game Boy Advance games to ''Diamond'' and ''Pearl'' by inserting a Game Boy Advance cartridge into the Game Boy Advance cartridge slot of the Nintendo DS while ''Diamond'' or ''Pearl'' is in the DS slot. After six Pokémon are uploaded from the cartridge, they are sent to the Pal Park, an area where the player can capture the transferred Pokémon.This feature cannot be used on a Nintendo DSi, as the DSi lacks a Game Boy Advance cartridge slot. Pokémon uploads are restricted to six every twenty-four hours per Game Boy Advance cartridge, and the player must capture the uploaded Pokémon before performing another transfer. Pokémon transferred to ''Diamond'' and ''Pearl'' this way cannot be sent back to a Game Boy Advance cartridge. After completing a special mission in ''Pokémon Ranger'', the player will be able to send a Manaphy egg or Riolu from ''Ranger'' to ''Diamond'' or ''Pearl''.Wii
