Just watched The Ambition of Oda Nobuna. I'm not sure if Koei had any involvement with it, but they sure seem to throw several references to the actual Nobunaga's Ambition series....not that I've actually played any of them.
The show itself wasn't so bad, despite being full of girls it sure seemed like a more "serious" take on all the Sengoku-themed anime lately.
Though it sort of makes want a Pokemon Conquest anime...
