Warriors Orochi/Tear Jerker


 * The first game mentioned Cao Cao apparently died at Orochi's hand. He didn't, but we get to see why everyone believed that in Orochi's campaign in the second game, complete with a cutscene of Dian Wei wailing like a child as he carries the nearly dead Cao Cao away from the battle Orochi nearly killed him in, with a horrifying panorama of a battlefield full of the corpses of Wei army included.
 * This Salvation at Nagashino in the third installment to be a huge Tear Jerker. In this, you attempt to recruit Wang Yi, who is under the control of Kyomori Taira.
