Much like Generation III remade the Generation I games, the Generation II games also received much anticipated remakes in the form of HeartGold and SoulSilver, and through details revealed in the five main games, Generation IV is thus known to be contemporaneous with Generation II, occurring three years after Generation I and Generation III. Also like Generation II, the Generation IV games retain much compatibility with their Generation III counterparts, though in a different manner, and introduce many new Pokémon which are related to those of the previous three generations. Like previous generations, Generation IV focuses on one main region across three games, the Sinnoh region featured in Pokémon Diamond, Pearl, and Platinum on the Nintendo DS, released in 20 (and 20 outside Japan). Like Generation II followed from Generation I, Generation IV follows from Generation III, although it is unlike Generation II in that it is not a direct sequel ( Hoenn is inaccessible in all Generation IV games). The fourth generation (Japanese: 第四世代 fourth generation) of Pokémon games is the fourth set of Pokémon games released.
