ESRB description of XB3 is up. T for Language, Mild Blood, Suggestive Themes, and Violence. Make of it what you will.
>This is a role-playing game in which players follow fighters through a conflict between two nations. From a third-person perspective, players complete quests and engage in melee battle against enemies (e.g., animals, creatures, human boss characters). Combat is highlighted by impact sounds, explosions, and cries of pain. Cutscenes depict further instances of violence: characters impaled by sword; a character shooting herself off screen; a man stabbing himself off screen. A handful of scenes depict blood (e.g., droplets falling from a wounded character; drips of blood on a character's face). Some fantasy characters/creatures are designed with revealing armor and/or anatomy (e.g., deep cleavage, partially exposed breasts). The words “sh*t,” “ar*ehole,” and “b*tch” appear in the dialogue.
For comparison, XBDE is T for Blood, Mild Language, Partial Nudity, Use of Alcohol and Tobacco, Violence
>This is an adventure role-playing game in which players lead characters on a mission to save their worlds from destruction. As players explore fantasy environments and interact with characters, they use swords and magical projectiles to defeat various creatures (e.g., dragons, wolves, dinosaurs, giant robots) and human-like enemies in melee-style combat. Battles are accompanied by slashing sounds, colorful light effects, and depleted health meters. Some cutscenes include other instances of violence: a god-like character getting impaled with a spear; a dragon getting slashed with a sword. Some environments depict blood splatter on the ground; in one cutscene, a character is depicted coughing up blood. A handful of female characters are dressed in skimpy outfits that reveal large amounts of cleavage, and one cutscene depicts a male character's exposed buttocks. As the game progresses, players can accept a quest from a character who appears drunk, and slurring their speech (e.g., A drink . . . to shelebrate? *hic*”). One cutscene depicts a man smoking a cigar. The word "bastard" appears in the dialogue.
