Pokémon Diamond Version is role-playing games (RPGs) developed by Game Freak, published by The Pokémon Company and distributed by Nintendo for the Nintendo DS. With the enhanced remake Pokémon Platinum, the games comprise the fifth installment and fourth generation of the Pokémon series of RPGs. First released in Japan on September 28, 2006, the games were later released to North America, Australia, and Europe over the course of 2007.
Like previous Pokémon games, Diamond and Pearl chronicle the adventures of a young Pokémon trainer as he/she trains and battles Pokémon while also thwarting the schemes of a criminal organization. The games add many new features, such as Internet play over the Nintendo Wi-Fi Connection and changes to battle mechanics and Pokémon Contests, along with 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’ Pokédexes.
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 DS. It was forecasted to be released in Japan in 2005, but was shipped in 2006. 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.
