Here's something coming out of left field: the Pokèmon Company and Koei are teaming up to develop a crossover Nintendo DS game featuring Pokèmon and grand strategy RPG Nobunaga's Ambition. Feudal warlord Oda Nobunaga, along with other military commanders, will utilize the famous pocket monsters to fight battles in Pokèmon + Nobunaga’s Ambition.
Early screenshots seem to suggest Pokèmon trainers have a specialty with using certain elemental Pokemon types. Pokèmon from all five current generations are appearing in Pokèmon + Nobunaga’s Ambition, including Mewtwo, Piplup, Articuno, Eevee, Groudon, and Zekrom.
Pokèmon + Nobunaga’s Ambition currently has a release set for spring 2012 in Japan.
