I think the early Rot3Ks had pretty decent AI, but can't speak to the later ones. The AI in the first of the series was excellent, but the options were also the most limited, as you might expect.

Naitō Masatoyo (1522-June 29, 1575) was a Japanese samurai of the Sengoku period. As one of Takeda Shingen's most reliable generals, he fought in many of the Takeda clan's battles. Masatoyo was born the 2nd son of Takeda Nobutora's senior retainer Kudō Toratoyo. He was first called Kudō Sukenaga. The family's fortunes fell when Toratoyo lost favor with Nobutora, and was killed by him. Sukenaga and his brother escaped the Takeda clan, and according to the predominant theory, they wandered around the Kantō region. After Nobutora was exiled by his son Takeda Shingen, Shingen recalled the Kudō brothers, reinstating their lands and permitting the family's restoration. Shingen also formally excused Toratoyo of any wrongdoing and sent a letter of apology and money to the family. Furthermore, the Kudō were given command of 50 cavalry, and granted the rank of samurai-taishō. In 1566 he was given Minowa Castle in Kōzuke Province after it fell to the Takeda. At Mikatagahara he led a charge into the Tokugawa ranks and was at the forefront of the fighting at Nagashino (1575). He had opposed the attack at Nagashino and in the course of the battle was shot many times by arrows before being beheaded by Asahina Yasukatsu. He had been noted for his warm disposition and his equally impressive talents in warfare and administration. He had even been a mentor to the young Katsuyori, Takeda Shingen's fourth son. At Nagashino, after disagreeing with Katsuyori, he rushed into battle, dying an honorable death.

However, his fame was subsequently eclipsed by one of his descendants, who regularly appears on GameBanshee under the guise of Minerva.
