Role in Games

 * "I didn't think you were a mere slave to power."
 * -Mitsunari Ishida on Sima Yi in Warriors Orochi 2.

Dynasty Warriors
As the Dynasty Warriors series progressed, Sima Yi grew from an ordinary Wei strategist to a cunning and arrogant man. In Dynasty Warriors 5, Sima Yi develops a deep rivalry with Zhuge Liang of Shu. The two fought many battles against each other, each one proving to make the rivalry worse. Sima Yi was able to defeat Ma Su, an officer under Zhuge Liang. In the end, it comes down to the Battle of Wu Zhang Plains to determine who is the better of the two. The battle, no matter what installment, has many twists and turns, thus no side is able to gain a full advantage. During the battle, Sima Yi senses Zhuge Liang's death and sends out all of his forces. His ending in Dynasty Warriors 5 shows him meeting with Cao Pi, after which he returns to the dark hallways and vows to take the throne.

In Dynasty Warriors 6, his storyline revolves around him using Cao Cao's ambition as a means of gaining control of the land by any means necessary. He participates in battles similar to those in previous games, eventually allowing Cao Cao to take control of the land, after which Sima Yi is placed to guard Han Zhong. Shortly after, he starts a rebellion and unites any officers under him, which includes Zhang He and Xu Huang. Claiming victory, he slays Cao Cao and ascends the throne. During his rule, he vows to create a world that has never been seen before, honoring his lord's last order.

Warriors Orochi
In the original Warriors Orochi, Sima Yi serves Orochi faithfully, gladly breaking his bonds with Wei. He can be unlocked at the Gaiden stage, Odawara Castle in the Samurai storyline. If the player successfully executes two fleeing officers, therefore ruining Sima Yi's trap, Sima Yi will be in awe of the Coalition's genius, and joins their cause. In Warriors Orochi 2, Sima Yi works in Masamune's army. In the Samurai Warriors story, at Chang Ban, the player and Shingen Takeda can outwit Sima Yi, and, he again, joins the Coalition.

Kessen
Sima Yi is a confident and talented magician for Wei in Kessen II. He serves as a strategist and adviser for Cao Cao. He is first seen strutting into Cao Cao's throne room midway through the game, wondering why he can't find the "great hero of the land". He bluntly ventures that Cao Cao is the cause of the land's natural disasters as they continue due to the conqueror's selfish desires. He states that the lord will lose to Liu Bei if this continues, which gets an angered response from Cao Cao. Sword drawn to the offender, he growls for his name to which Sima Yi politely bows and introduces himself. Cao Cao likes the sorcerer's fearless nature and recruits him on the spot. His battle strategy is one of the best ways to fend off an angry Ma Chao.

Dynasty Warriors
In Dynasty Warriors 6, Sima Yi's weapon of choice are gloves that protrude long and thin of wire from his fingertips. Despite the claws' small and fragile appearance, the wires that protrude from them have good range. His deadlock attack shows that these wires are strong enough for him to hook them into an opponent, lift them, and smash them to the ground. He gains a good amount of crowd control attacks, especially during higher Renbu levels, and relies considerably less on magic than before. In some ways, he resembles a long range character, as his attack efficiency is somewhat weakened while he is close to his opponent. However, this setback can be bypassed if the player has mastered when to properly evade.
