Pokémon Conquest, a name-change from Pokémon + Nobunaga's Ambition in Japan, is being released in North America on June 18 for the DS.
"In Pokémon Conquest, players take on the role of a young Warlord who is linked with a Pokémon. Together, they must set out to recruit Warrior allies to strengthen their growing kingdom. Along their journey, players will encounter a variety of Pokémon, as well as Warriors and Warlords inspired by the Japanese feudal era. The game contains nearly 200 Pokémon, including many from the recent Pokémon Black Version and Pokémon White Version games, which have sold more than 4 million copies combined in the United States. As the battlefield unfolds in Pokémon Conquest, players must choose the correct Pokémon type to inflict maximum damage on their opponents. In the turn-based skirmishes, players choose different tactics for intense six-on-six battles, and battle conditions can change on every turn, keeping players on their toes in anticipation of what will happen next."
