T rated (short for Teen rated), are games that are mostly suited for ages 13 and higher. This is an ESRB rating and is what most Star Wars games are rated. Only games such as LEGO Star Wars and Star Wars: Rebellion are Star Wars games that aren't rated T.
Reasons for games being rated T[]
Most T rated games generally consist of violence and shooting and possibly mild language and drug references. But thats not always the case. Some games are rated T because of blood, for example, Star Wars: Knights of the Old Republic II: The Sith Lords. Other possible reasons for a game to fall under the T rating by ESRB would be Suggestive Themes, Song Lyrics, and Fantasy Violence.
